| abstract | 6-Aminopenicillanic acid, 3-acetoxymethyl-7-amino- Delta 3cephem-4-carboxylic acid and 3-methyl-7-amino- Delta 3-cephem-4car-boxylic acid and esters thereof are reacted with ketene in an aqueous or inert non-aqueous solvent at a temperature between about 5* and about 35* C. to provide the corresponding acetamido derivatives in superior yields. 6-Acetamidopenicillanic acid, 3acetoxymethyl-7-acetamido- Delta 3-cephem-4-carboxylic acid, 3methyl-7-acetamido- Delta 3-cephem-4-carboxylic acid and the esters thereof are useful intermediates for the preparation of cephalosporin antibiotics. |
