摘要：
The base-catalyzed reaction between isatins and N-Boc-3-pyrrolin-2-one yields Morita-Baylis-Hillman (MBH) adducts instead of the expected aldol products in good to high yields (up to 97%). Various organic and inorganic bases are efficient catalysts for this reaction. Our study excluded the Morita-Baylis-Hillman mechanism for the formation of the MBH-type products. The MBH products are most likely formed as a result of the subsequent isomerization of the original aldol products between isatins and N-Boc-3-pyrrolin-2-one. (C) 2013 Elsevier Ltd.
