An iridium-catalyzed asymmetric allylic substitution reaction with 2-alkoxy carbonyl-1,3-dithianes has been achieved with high regio- and enantioselectivities. The transformation provides a new method for the enantioselective α-functionalization of dithianes. The corresponding dithiane-containing products are easily converted into many other derivatives with high yields and enantioselectivities.

铱催化的烯丙基取代对1,3-二硫醚的对映选择性α-官能化。

用2-区域烷氧基羰基-1,3-二硫杂环丁烷进行铱催化的不对称烯丙基取代反应，具有很高的区域选择性和对映选择性。该转化为二噻烷的对映选择性α-官能化提供了一种新方法。相应的含二噻吩的产物易于转化成许多其他具有高产率和对映选择性的衍生物。
