L-proline catalyzed Michael additions of thiophenols to alpha,beta-unsaturated compounds, particularly alpha-enones, in the ionic liquid [bmim]PF6.

Peter Kotrusz1, Stefan Toma.   

Abstract

L-proline catalyzed additions of 13 different thiols to 11 different alpha-enone Michael acceptors in [bmim] PF(6 )are reported. Reasonable to high yields of the reaction products were isolated in most cases.
