Palladium-catalyzed alkene difunctionalization reactions between alkenes bearing tethered aryl or alkenyl triflates and enolate nucleophiles are described. The transformations form two C-C bonds, a ring, and up to two stereocenters, while producing substituted cyclopentane derivatives that contain appended carbonyl functionality. Products are formed with up to >20:1 diastereoselectivity, and formation of sterically congested bonds between quaternary carbon atoms is feasible.
描述了钯催化的带有连接芳基或烯基三氟甲磺酸酯的烯烃与烯醇盐亲核试剂之间的烯烃双官能化反应。这些转化形成了两个C-C键、一个环和多达两个立体中心，同时生成含有附加羰基官能团的取代环戊烷衍生物。产物以高达>20:1的非对映选择性形成，并且在季碳原子之间形成空间拥挤的键是可行的。
