A photoredox/palladium-cocatalyzed enantioselective alkylation of racemic secondary carbonates with 4-alkyl-1,4-dihydropyridines under visible light irradiation has been developed. The present study provides a method for the preparation of optically active diarylalkanes from racemic diarylmethyl carbonates by a dynamic kinetic asymmetric transformation (DYKAT). This photoredox/palladium dual catalysis strategy expands the scope of the asymmetric Pd-catalyzed benzylic substitution reaction and serves as its potential alternative and complement.

碳酸苄酯与4-烷基-1,4-二氢吡啶类化合物的光氧化还原/钯共催化对映选择性烷基化

已经开发了在可见光下用4-烷基-1,4-二氢吡啶进行光氧化还原/钯催化的外消旋仲碳酸酯的对映选择性烷基化。本研究提供了一种通过动态动力学不对称转化（DYKAT）由外消旋碳酸二芳基甲酯制备旋光性二芳基烷烃的方法。这种光氧化还原/钯双重催化策略扩大了不对称钯催化的苄基取代反应的范围，并作为其潜在的替代和补充。
