An efficient approach for synthesizing a series of 2-sulfide carbapenems has been developed using two successive Cu(I)-catalyzed cross-couplings in a single pot. The method involves highly selective intramolecular coupling of lactam and dihaloalkene using 2,2'-bipyridine as a ligand, followed by intermolecular C-S formation in the presence of another ligand (1,10-phenanthroline, PPh 3) and mercaptan
使用单个罐中两个连续的Cu(I)催化的交叉偶合,已经开发了一种合成一系列2-
硫化碳青霉烯的有效方法。该方法包括使用
2,2'-联吡啶作为
配体进行内酰胺和二卤代烯烃的高选择性分子内偶联,然后在另一种
配体(1,10-
