Micellar promiscuity: an expeditious approach to Morita–Baylis–Hillman reaction
摘要:
An accelerated and efficient method for Morita-Baylis-Hillman (MBH) reaction in aqueous cationic micellar solution under ambient conditions has been developed. The present method holds promise for future use of cyclic and acylic MBH-adducts of general utility in total synthesis of natural products in a robust fashion. (C) 2013 Elsevier Ltd.

A convenient and facile stereoselectivesynthesis of (E)- and (Z)-trisubstituted alkenes has been achieved by treatment of unactivated Baylis–Hillmanadducts with NaBH4 in the presence of CuCl2·2H2O at room temperature for 15 min.

The Friedel-Crafts reaction of the Baylis-Hillman adducts
A simple and convenient methodology for the stereoselective construction of 2-benzyl substituted trisubstituted olefins via sulfuric acid catalyzed Fredel-Crafts reaction of benzene with Baylis-Hillmanadducts is described.
