Abstract
NEW MATERIAL:Cephalosporins shwon by the formula I (R1 is OH, alkoxy, acyloxy, etc.; R2 is H, alkyl, halogen, COOH, carboxyl-protecting group, etc.; R3 is H, acetoxy, carbamoyloxy, etc.; n is 0 or 2) and its pharmacologically acceptable salt.
EXAMPLE: 7β- [ ( 3-benzenesulfonyloxyisooxazole-5-yl ) methylthioacetamido ] -7α- methoxy-3-(1-methyl-1H-tetrazole-5-yl)thiomethyl-3-cephem-4-carboxylic acid.
USE: An antibacterial agent having a wide range of antibacterial spectrum.
PROCESS: For example, a compound shwon by the formula II (M is protecting group, etc.) is reacted with a compound shown by the formula III (R2' is R2 except for COOH; X is hologen), and, if necessary, the protecting group is removed, to give a compound shown by the formula I.
