Abstract
Relates to N-acyl derivatives of the nucleus of Cephalosporin C, Cephalosporin CC or a Cephalosporin CA compound, such as Cephalosporin CA (pyridine), having the general formula R1R2. CH.CO.X in which R1, R2 represent a hydrogen atom, an alkyl group, a phenyl group, a substituted phenyl group or a group of structure R3-O-, in which R3 represents an alkyl group, a phenyl group or a substituted phenyl group, and are the same or different, and X represents the residue of the nucleus of Cephalosporin C, Cephalosporin CC or a Cephalosporin CA compound, and to sodium, potassium and ammonium salts thereof. The derivatives may be prepared by treating the nucleus of Cephalosporin C, Cephalosporin CC or a Cephalosporin CA compound with an acylating agent capable of acylating the amino group of the nucleus with the group R1R2.CH. CO, prepared acylating agents being acid chlorides. Examples describe the production of 7-phenylacetamido- and 7-a -phenoxypropionamido-cephalosporamic acid, and of the phenylacetyl derivatives of the nuclei of Cephalosporin CA (pyridine) and Cephalosporin CC. Specification 810,196 also is referred to.
