The invention relates to novel compounds of high antimicrobial activity, and to novel intermediates for the preparation of said compounds, said intermediates being of the formula: ##STR1## in which W is a protective amino group and Y is --S--Ag or --S--R.sup.5, wherein R.sup.5 is a mercapto-protective group, or W and Y are combined together to form a group of the formula: ##STR2## wherein R.sup.a is a residue excluded a radical "--CONH--" from acylamino, and Z is a group of the formula: ##STR3## wherein R.sup.3 is carboxy or a protected carboxy group and Z.sup.1 is azido, hydroxy, amino, formamido, isocyano or halogen, provided that, when W and Y are combined together to form a group of the formula: ##STR4## wherein R.sup.a is as defined above, then Z is a group of the formula: ##STR5## wherein R.sup.3 is as defined above, or salts thereof.
本发明涉及高抗微生物活性的新化合物,以及用于制备所述化合物的新中间体,所述中间体的化学式为:##STR1## 其中W是一种保护性氨基基团,Y是--S--Ag或--S--R.sup.5,其中R.sup.5是硫醇保护基,或W和Y结合在一起形成化学式为:##STR2## 其中R.sup.a是除去酰胺基团"--CONH--"的残基,Z是化学式为:##STR3## 其中R.sup.3是羧基或保护羧基基团,Z.sup.1是偶氮基、羟基、氨基、甲酰胺基、异氰基或卤素基团,但当W和Y结合在一起形成化学式为:##STR4## 其中R.sup.a如上定义时,Z是化学式为:##STR5## 其中R.sup.3如上定义,或其盐。
