We report a simple procedure for the indium-mediated addition of 4-bromocrotonic acid to a variety of aldehydes and ketones. In all instances the reaction proceeds exclusively with α-addition and typically in moderate to good yields (42–100%). The effect of solvent is minimal allowing a wide choice of conditions (methanol, ethanol, ethanol/water, water, tetrahydrofuran, and the ionic liquid [bmIm][BF4])
