The asymmetric reduction of benzophenones multisubstituted at the ortho-positions was achieved via hydrosilylation catalyzed by in situ generated chiral diamine–Zn–diol complexes under mild conditions, wherein polymethylhydrosiloxane (PMHS) served as a safe and inexpensive source of hydride.
在温和的条件下,通过原位生成的手性二胺-锌-二醇络合物催化氢化硅烷化,可以实现邻位多取代的二苯甲酮的不对称还原,其中聚甲基氢硅氧烷(PMHS)是一种安全且廉价的氢化物来源。
