We describe the preparation of isomerically pure 2′-Z-chloromethyl and 2′-Z-bromomethyl anhydropenicillins 2a and 2b, from 6,6-dibromo 2β-(chloromethyl) and 2β-(bromomethyl)-2α-methyl-penam-3α-carboxylic acid through the Wolfe rearrangement of anhydropenicillins.
我们描述了由6,6-二溴2β-(氯甲基)和2β-(溴甲基)-2α-甲基-penam-3α制备异构纯的2'-Z-氯甲基和2'-Z-溴甲基脱水青霉素2a和2b -羧酸通过无水青霉素的沃尔夫重排。
