IPC: C07D501/20
Filed: 1968-04-05
Abstract: 1,265,315. Benzylamine and collidine cephalosporanates. GLAXO LABORATORIES Ltd. 26 March, 1969 [5 April, 1968; 21 March, 1969], Nos. 16593/68 and 15081/69. Heading C2A. In a process for preparing pure crystalline 7 - α - aminoarylacetamido - cephalosporin derivatives of Formula (I) wherein Ar is an aromatic group (including heterocyclic aromatic) which may be substituted; R<SP>1</SP> is -H, -OH, -OAc or the residue of a substituting nucleophile, the corresponding cephalosporin derivative having the amino group protected as a group -NR<SP>2</SP>R<SP>3</SP> where R<SP>2</SP> is a conventional protecting group and R<SP>3</SP> is H or a conventional protecting group which may form a ring system with R<SP>2</SP> and the nitrogen atom, is converted to a salt with benzylamine or a collidine (e.g. symmetrical 2,4,6-trimethylpyridine), the salt is then separated, converted back to the cephalosporanic acid, and the protecting groups are removed to give the required derivative of Formula (I). The novel benzylamine and collidine salts are prepared by reacting the amino-protected cephalosporanic acid with the amine in a solvent such as water, acetone, methyl ethyl ketone, methyl isobutyl ketone, or ethyl- or butylacetate, preferably at slightly elevated temperature (e.g. 25-60‹ C.) with agitation of the medium. The amine may be added as such or in solution to a solution of the cephalosporanic acid. The salt crystallizes out on cooling, if necessary after reducing the solvent volume or adding a non-solvent, e.g. diethyl ether, and may be purified by re-crystallization. The group Ar in Formula (I) may be phenyl, optionally substituted with halo, hydroxy, C 1  to C 6  alkyl, nitro, amino or substituted amino, C 1  to C 6  alkanoyl, C 1  to C 6  alkoxy or C 1  to C 6  alkylmercapto, or may be a thienyl group. Protected amino groups include urethane, arylmethyl (e.g. trityl)-amino, arylmethyleneamino, sulphenylamino and enamine moieties, the protecting group preferably being t - butoxycarbonyl or #,#,# - trichloroethoxycarbonyl. The amino-protected cephalosporanic acid starting material may be prepared by acylating a 7-aminocephalosporanic acid with an amino-protected α-aminoarylacetic acid or an acylating derivative thereof. The benzylamine or collidine salt is converted to the free acid by treatment with an acid, preferably an aqueous strong mineral acid whose benzylamine or collidine salt is water-soluble, so that the cephalosporanic acid produced may be separated by extracting it with a water-immiscible organic solvent. If appropriate, this acid treatment can effect simultaneous removal of certain of the amino-protecting groups, e.g. most urethane-forming groups, enamine-forming groups, arylmethyl and sulphenyl groups.

Abstract: 1,266,328. Tube mills; grinding cement. F. L. SMIDTH & CO. A.S. 5 June, 1969 [17 Sept., 1968], No. 44097/68. Heading B2A. Apparatus for grinding and drying material in particular chalk and clay containing unwanted flints in the manufacture of cement comprises a rotating tumbling mill 7, means 4, 5, 6 to introduce raw material and means 9, 10 to introduce hot gas through the inlet trunnion of the mill, a riser pipe 12 acting as a separator with its lower end communicating with an outlet trunnion of the mill, and the upper end communicating via a cyclone 13 with the suction side of a fan 15. Atmospheric air is prevented by flexible seals from entering a casing 5 which feeds the mill 7. The exit gas from the fan 15 is cleaned by an electro-precitator 18. The product is discharged from the cyclone 13 and the filter 18 to a conveyor 24. Some of the dry fine product is however discharged from cyclone 13 via a pipe 21 and is conveyed by a belt 29 to an inlet screen 31 for the mill, where it is distributed over the sticky feed material, and thus reduces its stickiness. Coarser material separated in riser pipe 12 falls via a pressurized discharge chamber 34 on to the conveyor 29. Large unground flint bodies are rejected by the screen 31. In a second embodiment, Fig. 2 (not shown) material is predried in a pipe 38, see Fig. 3, prior to milling and two flows of dried material 28 and (48) from two cylones 39, 13 are available for distribution over the incoming sticky material. In a third embodiment an additional screen 49 is provided for material separated by the cyclone 39 and the screen residue is added to material flowing to the mill.

Date Dec. 14, 1995Novel backbone cyclized peptide analogs are formed by means of bridging groups attached via the alpha nitrogens of amino acid derivatives to provide novel non-peptidic linkages. Novel building units disclosed are N alpha ( omega -functionalized)amino acids constructed to include a spacer and a terminal functional group. One or more of these N alpha ( omega -functionalized) amino acids are incorporated into a peptide sequence, preferably during solid phase peptide synthesis. The reactive terminal functional groups are protected by specific protecting groups that can be selectively removed to effect either backbone-to-backbone or backbone-to-side chain cyclizations. The invention is exemplified by backbone cyclized bradykinin antagonists having biological activity. Further embodiments of the invention are somatostatin analogs having one or two ring structures involving backbone cyclization.
