A series of chiral bifunctional phosphinothioureas derived from L-amino acids have been developed to promote the enantioselective intramolecular Morita-Baylis-Hillman reaction. The process afforded the cyclic hydroxyl enones with up to 84% ee and good yields under mild conditions. (C) 2010 Elsevier Ltd. All rights reserved.
