Our previously disclosed ruthenium-catalyzed carbon-carbon bond forming reactions between propargylic alcohols and alkenes via an allenylidene-ene type pathway have been successfully applied to an enantioselective intramolecular cyclization for a variety of chiral heterocycles such as chromane, thiochromane, and 1,2,3,4-tetrahydroquinoline derivatives (up to 99% ee) by use of a suitable optically active
我们之前公开的钌催化炔丙醇和烯烃之间通过丙二烯-烯型途径形成碳-碳键的反应已成功应用于各种手性杂环如色烷、硫色满和 1,2 的对映选择性分子内环化, 3,4-四氢喹啉衍生物(高达 99% ee)通过使用合适的光学活性二钌配合物作为催化剂。本文描述的方法成为一种新的手性杂环合成方法,其结构广泛存在于许多天然和生物活性化合物中。
