Patent GB-788137-A (GB)
Title: Manufacture of monoalkyl- and monocycloalkyl-aminoalkyl esters
Filed: 1956-03-05
Abstract: Monoalkyl- or cycloalkyl-aminoalkyl esters are prepared by a process comprising reacting a tertiary amino lower alkanol having one of the amino hydrogens replaced by lower alkyl or cycloalkyl, and the other by a hydrogenolysable group, with an acylating agent to form an ester, and thereafter subjecting said ester to a hydrogen reducing atmosphere to remove the hydrogenolysable group, and recovering the monalkylaminoalkyl ester uncontaminated by amide products (lower means 1-6 carbon atoms).  In particular, esters of the formula: <FORM:0788137/IV (b)/1> wherein R is lower alkyl, R1 is bivalent lower aliphatic hydrocarbon, and R11 is lower alkyl or cycloalkyl, are made by reacting an alkanol of the formula: <FORM:0788137/IV (b)/2> where A is benzyl, benzhydryl, a -menaphthyl, b  - menaphthyl, carbobenzoxy, carbo-allyloxy, or halocarbobenzoxy, with an acylating agent of the formula: <FORM:0788137/IV (b)/3> where B is nitro or amino, and X is halogen or lower alkoxy to form an ester of the formula: <FORM:0788137/IV (b)/4> and subjecting the ester to a hydrogen reducing atmosphere to remove group A.  The aminoalkanol starting materials may be prepared by reductive alkylation with benzaldehyde, formaldehyde, propionaldehyde or cyclohexanone of a monoalkyl or aralkyl aminoalkanol, or by condensation of a benzylalkylamene with an alkylene oxide.  In examples: (1) anisoyl chloride is reacted with 2-(benzyl-n-propylamino) ethanol, followed by hydrogenation to give 2 - (n - propylamino) - ethyl 41 - methoxybenzoate hydrochloride; (2) 3 - nitro - 4 - n-butoxybenzoyl chloride is reacted with 2-(benzyl - n - propylamino) ethanol, 2 - (benzylmethylcyclohexylamino) ethanol, 1 - (benzylmethylamino) - 2 - propanol, 3 - (benzylmethylamino)-1 - propanol, 3 - (cyclohexylcarbobenzoxyamino) propanol, 2 - (benzylethylamino) ethanol, 2 - (benzylisopropylamino) ethanol, 2-(benzyl - n - butylamino) ethanol, 2 - (benzyl-n - propylamino) - 1 - butanol, 1 - (benzyl - n-propylamino) - 2 - propanol, or 2 - (benzylisobutylamino) ethanol, followed in each case by hydrogenation, which splits off the benzyl or carbobenzoxy group and reduces the nitro to amino; also in examples: (3) 4-nitrobenzoyl chloride is reacted with 1-(benzylmethylamino)-2 - propanol or 2 - (benzyl - n - butylamino) ethanol, followed by hydrogenation, which again splits off benzyl and reduces nitro to amino.

Title: Processes of preparing intermediates in the preparation of penicillamine
IPC: C07D277/06
Filed: 1947-03-13
Abstract: 2-Lower alkyl-5 : 5-dimethyl-D 2-4-thiazoline-carboxylic acids are prepared by treating a 2-lower alkyl-4-isopropylidene-5 oxazolone or an a -lower aliphatic acylamino-b  : b -dimethylacrylic acid with absolute methanol in which sodium is dissolved, saturated with hydrogen sulphide.  By the term "lower" alkyl or "lower" aliphatic is meant that the group contains 1-4 carbon atoms.  Preferably the reaction is carried out between 0 DEG  C. and room temperature, hydrogen sulphide is passed in during the reaction and for about sixteen hours after and the reaction mixture is neutralized with hydrogen chloride in methanol, the solvent being finally removed by heating under reduced pressure.  The product or the crude reaction mixture after evaporation of the solvent is warmed with water to give an N-lower aliphatic acyl-dl-penicillamine which is reacted with an aqueous hydrohalic acid in an inert atmosphere to give a dl-penicillamine hydrohalide and treated with pyridine in methanol to give dl-penicillamine.  In examples: (1) 2-methyl-4-isopropylidene-5-oxazolone, prepared by the reaction of a -amino-b -methoxyisovaleric acid with acetic anhydride in the presence of triethylamine, is added to a 0.6 per cent solution of sodium in methanol saturated with hydrogen sulphide at 0 DEG  C., hydrogen sulphide being passed through the solution for sixteen hours after the addition, the 2 : 5 : 5-trimethyl- D 2-4-thiazoline-carboxylic acid produced is converted to N-acetyl-dl-penicillamine by warming in water; and (2) crude azolactone prepared from a -amino-b -methoxyisovaleric acid as in (1) is treated with a methanol solution of sodium saturated with hydrogen sulphide, and the resulting compound is converted to N-acetyl-dl-penicillamine which is converted to dl-penicillamine hydrochloride by warming with hydrochloric acid and finally treated with pyridine to give penicillamine.  a -Lower aliphatic acylamino-b : b -dimethyl-acrylic acids are prepared by converting dl-valine to an N-a -haloacyl derivative forming the addition compound thereof with a pyridine base and converting this to the corresponding a -lower aliphatic acylamino-b  : b -dimethylacrylic acid, or by reacting dimethylacrylic with mercuric acetate, brominating the addition product formed, treating with ammonia to form the a -amino-b -methoxyisovaleric acid and reacting with a lower aliphatic acyl anhydride to form the a -lower aliphatic acylamino-b  : b -dimethylacrylic acid.

A method of reducing metal strip comprises feeding the strip 1 by bridle rollers to a first back-up roll 5, through an S-shaped path defined by a pair of work rolls 7, 8, around a second back-up roll 6 and around further bridle rollers. The bridle rollers and work rolls are driven by conventional means through gearing (12)-(23), Fig. 2 (not shown). The work rolls 7, 8 are supported in a housing 29 mounted for rotation about an axis 30 to vary the angle a. The backup rolls 5, 6 are supported in frames (36), (37), Fig. 3 (not shown). The frame (36) is pivotally connected to a fixed support (42) and the separation of the rolls 5, 6 is adjustable by means of a screw (45) on the frame (36) and a nut (46) fixed on the frame (37), the frame (37) being held in position by a bar (44). To insert the strip into the apparatus, the rolls 5, 6 are separated and the housing 29 rotated through 180 degrees by a handle (65), Fig. 5 (not shown), so that the strip can be threaded directly between the rolls. The work rolls 7, 8 are returned to their original position and the back-up rolls 5, 6 moved towards each other. The strip 1 is tensioned by the bridle rollers (3), (4), (9), (10). As the tension increases, the strip 1 pulls the rolls 7, 8 into contact with the strip at positions 30, 32, 33 to form three passes. A pair of load cells (53), Fig. 9 (not shown), are carried by cross-heads (54). The cross-heads (54) are adjustable so that each load cell has an equal load. The bearings of the work roll 8 are mounted in axle boxes (63), Fig. 6 (not shown), to allow the roll to float in the plane 28. The plane 31 may be horizontal, Fig. 11 (not shown), and the rolls 7, 8 may be of different diameters, Fig. 10 (not shown).

Abstract: 724,815. Machine tool details. SENECA FALLS MACHINE CO. March 17, 1953, No. 7403/53. Class 83 (3). Work-transfer mechanism for a machine tool comprises a carriage having a normal loading position adjacent the working axis of the machine, means on the carriage (a) to remove a finished workpiece from the machine; (b) to insert a new workpiece into the machine; means to shift the carriage axially to a replenishing position and to thereupon release the finished work, supply a new piece of work and thereafter return the carriage to its normal loading position. A carriage 25, Figs. 1 and 2, of triangular cross-section, with the apex pointing downwardly, is suspended by runners 26 from overhead rails 21. The carriage is moved alternately over the working station and to a loading and discharging position clear of the machine, by an electric motor M5 rotating a screw 61 with which engages a roller 60 secured to the carriage. Front and rear inclined slides 31, 31a, respectively, are arranged on the carriage, each of which carries a three-armed lever 36, Fig. 4, pivoted at the lower end thereof. The levers carry work-gripping jaws which are arranged identically, the front lever effecting insertion of new work while the rear operates on finished work. Each slide is moved in its guideway by an electric motor (M3 for front slide), Fig. 4, through worm gearing 50, 51, and an arm 54 having a roller 55 which engages a slot 56 in a member 57 secured to the slide. Along the lower arm of the lever 36 are work-gripping jaws 32 ... 34, operated by air cylinders 38. The arm 36a of the lever 36 carries a roller 40 which engages a cam slot in a member 41 secured to the carriage 25, similarly, the arm 36b carries a roller 42 engaging a cam slot in a member 43 secured to the carriage; the latter roller comes into operation as the first roller reaches the end of its cam slot. The combined effect of these cam slots is to tilt the work as it is moved downwardly or away from the lathe axis by the motion of the slide 31 or 31a respectively. On feeding new work the blank is tilted down at its chuck end and then finally aligned with the tailstock centre. When the carriage 25 is moved to the extreme right-hand position away from the machine, the feeding and removing levers are brought into alignment with a loading runway 70, Fig. 7, which has a tilt operated by an air cylinder 75 to enable an end workpiece W to be raised to a position where it may be gripped by the fingers on the front lever. Similarly the finished work W2 is collected and moved on to a discharge runway 80 by an air. cylinder operated tilt 82. The operations are controlled by ratchet-operated switches and solenoid-operated valves correlated to the machining operations on the work.

Patent GB-816908-A (GB)
Title: Amino-acid salts and compositions of basic antibiotics
Filed: 1956-03-09
Abstract: The invention relates to the leucine and N-acyl leucine salts of streptomycin, dihydrostreptomycin, neomycin and niomycin and of partial salts of said antibiotics with other acids.  At least one of the basic groups in the antibiotic should be replaced by the leucine or N-acyl leucine.  According to examples: (a) the leucine salt of neomycin is prepared by dissolving neomycin and leucine in water; (b) the leucine salt of streptomycin or dihydrostreptomycin is prepared by dissolving leucine and barium hydroxide in water adding streptomycin sulphate or dihydrostreptomycin sulphate, filtering off the barium sulphate and lyophilizing the filtrate; (c) the dl-leucine salts of streptomycin, dihydrostreptomycin and neomycin are produced by a similar method to that of (b), and (d) the alpha-N-acetylaminoisocaproic acid salts of streptomycin and dihydrostreptomycin are prepared by reacting the respective sulphates in aqueous solution with alpha-N-acetylamino-isocaproic acid in the presence of barium hydroxide.  The acyl derivatives of leucine preferably contain acyl radicals capable of increasing the solubility of the salts formed from the acyl leucine and the antibiotics.  The components of the salts (which include salts of leucine and N-acyl leucine) may be used in medicinal preparations (see Group VI).  The salts are less toxic medicinally than many of the known salts.ALSO:A therapeutic composition comprises leucine, an N-acyl derivative of leucine or a salt of either of these acids and streptomycin, dihydrostreptomycin, neomycin or viomycin, or a salt of one of these antibiotics, the quantity of leucine or the N-acylated leucine or salt thereof amounting to 5 to 150 and preferably 50 to 150 per cent of the antibiotic calculated as free base.  The composition may be an aqueous solution or a powder for dissolution in sterile water prior to injection.  Examples relate to an aqueous solution or powder obtained by dissolving or mixing leucine with streptomycin sulphate or dihydrostreptomycin sulphate.  The acyl derivatives of leucine preferably contain acyl radicals capable of increasing the solubility of the salts formed from the acyl leucines and the antibiotics, e.g. alpha - N - acetylaminoisocaproic acid.  Other medicaments such as other antibiotics, particularly penicillin, may be present.
