  Highly Enantioselective Ketone-Ene Reactions of Trifluoropyruvate: Significant Counterion Effect of the In(III)−PyBox Complex

  摘要：

  A chiral indium(III)-pybox complex catalyzed asymmetric ketone-ene reaction of trifluoropyruvate is described. Both aromatic and aliphatic 1,1-disubstituted alkenes reacted smoothly to give the enantioenriched tertiary homoallylic alcohols in good to excellent yields (up to 99%) and with excellent enantioselectivities (up to 98% ee).

  A highly enantioselective carbonyl-ene reaction of trifluoropyruvate catalyzed by a recyclable indium(III)-pybox complex in ionic liquid afforded trifluoromethyl-containing tertiary homoallylic alcohols with excellent yields (up to 98%) and enantioselectivities (up to 98% ee). Notably, this catalytic system can be recycled up to seven cycles.
