alpha-Amido sulfones undergo aza-Morita-Baylis-Hillman reaction efficiently with alkyl acrylates under neat conditions in the presence of DABCO at room temperature. These sulfones generate aryl imines in the presence of DABCO and form the corresponding adducts in high yields (85-94%) within 9-12 h. (C) 2008 Elsevier Ltd. All rights reserved.
