摘要：
The reaction of 2-(bromomethyl)acrylic acid (1) with different carbonyl compounds (2) [CH2O, (E)-CH3CH=CHCHO, (PrCHO)-C-i, (BuCHO)-C-t, PhCHO, CH3(CH2)(5)CHO, c-C6H11CHO, Ph2CHCHO, (CH2)(5)CO] and indium powder in a 1:1 THF:H2O mixture at room temperature affords, after acidic work-up with hydrochloric acid, the corresponding alpha-methylene-gamma-butyrolactones 3.
