Montmorillonite K10-microwave assisted stereoselective isomerisation of acetates of the Baylis-Hillman adducts furnished (E)-trisubstituted alkenes in high yields. A comparative study of this reaction with Mont-K10, ion-exchanged clay (Fe3+-Mont-K10) and acid treated regional natural Kaolinite clay and the efficiency of these clays in this reaction is described.
