Atom‐Economic Synthesis of Optically Active Warfarin Anticoagulant over a Chiral MOF Organocatalyst

Abstract

AbstractA novel chiral metal‐organic framework (MOF) organocatalyst has been developed, based on readily available MIL‐101 and the chiral primary diamine (1R,2R)‐1,2‐diphenylethylenediamine, by the post‐synthetic modification. Over the developed chiral heterogeneous catalyst the asymmetric synthesis of (S)‐warfarin with high enantioselectivity can be fulfilled on a gram‐scale (2.8 g) with excellent yield (92%) at low cost, making the synthesis method an ideal alternative to existing methods.magnified image
