Abstract: 1299648 Aminoxoazolines and compounds made therefrom SALK INSTITUTE FOR BIOLOCIAL STUDIES 26 May 1970 [6 June 1969] 25198/70 Heading C2C, and C2P An amino-oxazoline is prepared by mixing a reducing sugar with (a) cyanamide or (b) cyanogen plus ammonia, in a solvent therefor or in a suspension containing a solvent. The amino-oxazolines comprise (a) a sugar unit having a hemiacetal or carbonyl carbon atom and an adjacent C atom with a hydroxyl group attached thereto and (b) an amino-oxazoline ring unit, the hemiacetal and adjacent atom comprising a portion of the amino-oxazoline ring unit and being bonded to an N atom and an O atom in said ring unit, respectively. The term "sugar" covers glyceraldehyde and glycolaldehyde as well as conventional sugars, which may be mono-, di-, or poly-saccharides. The solvent is e.g. water optionally mixed with methanol, or a medium of pH 6-12. The amino-oxazdines thus produced may be further reacted with (a) an electrophlic reagent selected from cyanoacetylene, emthyl propiolate, a dimethyl acetylenedicarboxylate, and a haloacrylonitrile or (b) an electrophilic reagent selected from #-diketones and #-ketoesters (e.g. an alkyl acetoacetate, ethyl benzoylacetate, acetoacetaldehyde, acetylacetone and 3-methyl- 2,4-pentanedione) to produce a cyclo glycoside, which may be hydrolysed to produce a glycoside. The reducing sugars may be phosphated; thus in example 4, aqueous ammoniacal solutions of D-ribose-5-phosphate were warmed first with cyanamide and again after adding cyanoacetylene to yield cytidylic acid (1-α-D- ribofuranosyl cytosine - 5<SP>1</SP> - phosphate). In example 16 the use of D-arabinose-3,5-diphosphate yielded 2-amino-#-D-arabinofurano [1<SP>1</SP>,2<SP>1</SP> : 4,5] - 2 - oxazoline - 3<SP>1</SP>,5<SP>1</SP>-disphosphate, which when reacted with cyanoacetylene in the presence of water yielded the glycoside #-cytosine arabinoside-3<SP>1</SP>,5<SP>1</SP>-diphosphate.

Filed: 1946-08-28
Abstract: Alpha-(dichloroaryloxy)-aliphatic carboxylic acids or their esters, amides or like functional derivatives, especially dichlorinated phenoxy, cresoxy or napthoxy acetic and propionic acids, are produced by a direct two-stage chlorination of the aryloxy acids non-chlorinated in the nucleus, or their said derivatives, in a first stage with a substantially equimolecular amount of gaseous chlorine for the formation of the monochloro compound, and in a second stage by direct chlorination at a temperature higher than that used in the first chlorination with a second amount of gaseous chlorine substantially equal to that used in the first stage.  In examples: (1) phenoxy acetic acid is dissolved in glacinal acetic acid, a trace of iodine added and the solution cooled.  Gaseous chlorine is then introduced until an equimolecular proportion has been absorbed and the solution is then warmed to 60-80 DEG  C. and an equal amount of gaseous chlorine introduced.  On cooling 2, 4-dichlorophenoxy acetic acid crystallises; (2) a -(2,4-dichlorophenoxy)-propionic acid is obtained from a -phenoxy propionic acid as in (1), the second stage chlorination being effected at 50 DEG  C.; (3) 2-naphthoxy acetic acid suspended in glacial acetic acid with the addition of a trace of metallic iron is chlorinated as in (1), the first stage being effected at 40 DEG  C. and the second stage at 60 DEG  C., the product is probably the 1,4-dichloro compound.  Other starting materials specified are phenoxy acetic acid ethyl ester, phenoxy acetamide, a -phenoxy propionic acid ethyl ester, a -phenoxy-n-butyric acid, 1-naphthoxy acetic acid.  Specification 607,113 is referred to.
