  摘要：

  盼西林亚砜酯与异氰酸酯反应，生成相应的（取代）-2-氨基羧甲基青霉素，相应的（取代）-3-氨基羧甲氧头孢菌素或相应的3-甲基头孢菌素。这些产物的6-或7-侧链可以被裂解，得到相应的6-氨基（青霉素）或7-氨基（头孢菌素和头孢菌素）化合物，后者可以重新酰化，产生不同的6-酰基-2-氨基羧甲基青霉素，7-酰基-3-氨基羧甲氧头孢菌素和7-酰基-3-甲基头孢菌素。这些取代基团可以从（取代）-2-氨基羧甲氧青霉素或（取代）-3-氨基羧甲氧头孢菌素中去除，分别得到相应的游离2-氨基羧甲基青霉素或3-氨基羧甲氧头孢菌素。

  Penicillin sulfoxide esters are reacted with an isocyanate to produce the corresponding (substituted)-2-carbamoyloxymethylpenam, the corresponding (substituted)-3-carbamoyloxycepham or the corresponding 3-methylcephem. The 6- or 7-side-chain of these products may be cleaved to give the corresponding 6-amino (penams) or 7-amino (cephams and cephems) compounds, and the latter may be reacylated to produce different 6-acyl-2-carbamoyloxymethyl penams, 7-acyl-3-carbamoyloxy cephams and 7-acyl-3-methylcephems. The substituent groups may be removed from the (substituted)-2-carbamoyloxypenams or the (substituted)-3-carbamoyloxycephams to give the corresponding free 2-carbamoyloxymethylpenams or 3-carbamoyloxycephams, respectively.
