| titleOfInvention | Process for preparing 2-acyloxymethylpenams and 3-acyloxycephams |
| abstract | A process for preparing 2-acyloxymethylpenams and 3-acyloxycephams of the formulae 1 and 2 ##STR1## in which R represents the aliphatic, aromatic, or heterocyclic moiety of an amino-protecting group commonly employed in penicillin chemistry, R 1 is hydrogen or represents a carboxy-protecting group commonly employed in penicillin chemistry, and R 2 is hydrogen, C 1 -C 6 alkyl which may also be substituted with Cl, OCH 3 , or CN, and phenyl which may also be substituted with CH 3 , F, Cl, OCH 3 or NO 2 , by treating an unsym-azetidinone disulfide of the formula 3 ##STR2## in which R and R 1 are as defined above and R 4 is benzothiazol-2-yl or benzoxazol-2-yl with silver oxide, an acid of the formula R 2 COOH, and iodine, or with a silver salt of the formula R 2 COOAg and iodine, or with a Simonini complex of the formula R 2 COOI.R 2 COOAg, to obtain a mixture of the compounds of formulae 1 and 2, and optionally separating said mixture. |
