3-Acetoxymethyl-7-(iminoacetamido)-cephalosporanic acid derivatives

Compounds of the formula STR1 wherein R is hydrogen, R' is selected from the group consisting of alkenyl and alkynyl of 2 to 4 carbon atoms, A is selected from the group consisting of hydrogen, alkali metal and equivalents of an alkaline earth metal or magnesium and an organic amine base and the OR' group is in the syn position having antibiotic activity and process for their preparation.

3-Acetoxymethyl-7-(iminoacetamido)-cephalosporanic acid derivatives

Compounds of the formula STR1 wherein R is selected from the group consisting of hydrogen and groups easily removable by acid hydrolysis or hydrogenolysis, R' is selected from the group consisting of hydrogen, alkyl of 1 to 4 carbon atoms, alkenyl and alkynyl of 2 to 4 carbon atoms and groups easily removable by acid hydrolysis or hydrogenolysis, A is selected from the group consisting of hydrogen, alkali metal and equivalents of an alkaline earth metal or magnesium and an organic amine base with the proviso that when R' is a group easily removable by acid hydrolysis or hydrogenolysis, R is also and when R' is hydrogen, R also is hydrogen and the wavy line means the OR' group may be in either one of the two possible syn or anti positions having antibiotic activity and process for their preparation.
