general method is reported for the stereoselective preparation of highly functionalized allylic thioethers. This protocol is based on a Pd-catalyzed thiolation of modular vinyl cyclic carbonate substrates and features high (Z)-selectivity, good yields, minimal waste, ample product scope, and operational simplicity. A one-pot strategy was used for the stereoselective formation of pharma-relevant allylic sulfones
据报道,有一种通用方法可以立体选择性地制备高度官能化的烯丙基硫醚。该协议基于模块化乙烯基环状碳酸酯底物的Pd催化硫醇化反应,具有高(Z)选择性,高收率,废物少,产品范围广和操作简便的特点。一锅法用于立体选择形成与药物相关的烯丙基砜,它们是就地制备的硫醚前体衍生的。
