Herein, we report the enantioselective conjugate addition of organic boronicacids to α,β-unsaturated 2-acyl imidazoles using (R)-3,3′-I2-BINOL as the catalyst. The catalytic system shows high efficiency and tolerance to alkenylboronic acids and heteroarylboronic acids. The corresponding Michael addition products were obtained in moderate to excellent yields and with moderate to excellent enantioselectivities
