The highly efficient Rh/ZhaoPhos-catalysed asymmetric hydrogenation of γ-butenolides and γ-hydroxybutenolides was successfully developed. This protocol provides an efficient and practical approach to the synthesis of various chiral γ-butyrolactones, which are synthetically valuable building blocks of diverse natural products and therapeutic substances, with excellent results (up to >99% conversion
成功开发了高效 Rh/ZhaoPhos 催化的 γ-丁烯内酯和 γ-羟基丁烯内酯不对称氢化反应。该协议为合成各种手性 γ-丁内酯提供了一种有效且实用的方法,这些手性 γ-丁内酯是多种天然产物和治疗物质的合成有价值的构建块,具有出色的结果(高达 >99% 的转化率和 99% ee)。已揭示进一步的后续转化,以通过这种催化方法实现几种对映体富集药物的创造性和有效的合成路线。
