A ruthenium-catalyzed transfer hydrogenation of olefins utilizing formic acid as a hydrogen donor is described. The application of commercially available alkylidene ruthenium complexes opens access to attractive C(sp3)-C(sp3) bond formation in an olefin metathesis/transfer hydrogenation sequence under tandem catalysis conditions. High chemoselectivity of the developed methodology provides a remarkable
描述了利用甲酸作为氢供体的钌催化的烯烃的转移氢化。市售的亚烷基钌络合物的应用打开了在串联催化条件下烯烃复分解/转移氢化序列中有吸引力的C(sp3)-C(sp3)键形成的途径。所开发方法的高化学选择性为在温和的反应条件下还原各种官能化的烯烃提供了出色的合成工具。所开发的方法学用于药物戊氧基维林和苯环戊烷的正式合成。
