Abstract
A process for the preparation of acyloxyalkyl esters of 6- (α-aminophenylacetamido) penicillinic acid, 7- (α-aminophenylacetamido) deacetoxycephalosporinic acid or 7- (α-aminophenylacetamido) cephalosporinic acid, represented by the general formula: **(See formula)** where A represents: **(See formula)** where R1 and R2 each represent an alkyl, cycloalkyl, alkenyl or phenyl group without substituents or an alkyl, cycloalkyl, alkenyl or phenyl group substituted by a phenyl group, a phenoxy group or a halogen atom and R3 represents an atom of hydrogen or an acetoxy group; whose procedure consists in reacting the 6-phenylacetamidodeacetoxycephalosporic acid or 7-thienylacetamido cephalosporic acid acyloxyalkyl ester, represented by the general formula: R-CH2CONH-A where R represents a phenyl group or a thienyl group and A is as defined above, with a phosphorous halide to form the iminohalide compound, reacting the thus obtained iminohalide compound with a lower alcohol to form the iminoether compound, reacting the thus obtained iminoether compound with phenylglycyl chloride hydrochloride to form the addition compound, and then treating the addition compound with water or alcohol.
