An enantioselective aza-Michael reaction of benzotriazole to ,-disubstituted nitroalkenes has been developed. This reaction was catalyzed efficiently by a bifunctional thiourea catalyst, affording the corresponding products, bearing quaternary stereogenic centers, in moderate to high yields (up to 80%) and with high enantioselectivities of up to 95% ee.
