  The asymmetric Michael addition of 4-hydroxycoumarin to α,β-unsaturated ketones on water without organic co-solvents is reported to be catalysed by organic primary amines. The application of enantiomerically pure (S,S)-diphenylethylenediamine affords a series of important pharmaceutically active compounds in good to excellent yields (73–98%) and with good enantioselectivities (up to 76% ee) via reactions

  secondary amine amide catalysts were developed for the asymmetric Michael addition of 4-hydroxycoumarin to α,β-unsaturated ketones. A series of important biologically and pharmaceutically active compounds were obtained in excellent yields (up to 99 %) with high enantioselectivities (up to 89 % ee) under mild conditions. In addition, enantiopure product could be obtained by a single recrystallization

• Highly enantioselective synthesis of warfarin and its analogs by means of cooperative LiClO4/DPEN-catalyzed Michael reaction: enantioselectivity enhancement and mechanism

  The highly enantioselective synthesis of warfarin and its analogs was reported in this manuscript And a cooperative catalysis was observed in asymmetric primary amine-catalyzed Michael reaction for the enantioselective synthesis of warfarin and its analogs, which led to the finding of several cooperative catalyst systems combined with Lewis acid and primary amine, such as LiClO4/DPEN. In this Michael reaction of 4-hydrocoumarin, the cooperative catalyst system (LiClO4/DPEN) resulted in higher levels of stereoselectivity (up to 94%ee). Additionally, the mechanism of the enantioselectivity enhancement in the cooperative catalytic Michael reaction has been investigated by using of ESI-MS and the study of nonlinear effect.
