Abstract
7-Acylamino-7-methoxycephalosporins substituted in the 3-position with an acetoxymethyl, halomethyl or 3-thio-substituted-methyl substituent are reduced electrolytically to provide the corresponding 3-exomethylenecepham compound. For example, 7-(2-thienylacetamido)-7-methoxy-3-acetoxymethyl-3-cephem-4-carboxylic acid is electrolytically reduced to provide 7-(2-thienylacetamido)-7-methoxy-3-exomethylenecepham-4-carboxylic acid and a lesser amount of the corresponding 3-methylcephalosporin compound.
