PROCESS FOR PREPARING CEPHALOSPORIN COMPOUNDS
Celphalosporins (II, R1 = protected aminl; R2 = H, protective group; R3 = H, lower alkyl, alkylthio, alkoxy; Z = S) were prepd. by hydrolysis of III. Thus, 0.35 g (6R, 7R)-3-phosphono-carbamoyloxy-methyl-7- Z-2-(fur-2-yl)-2-methoxy-imino-acetamido ceph-3-em-4-carboxylic acid was treated at 40 C for...
