Asymmetric Michael Addition of Nitroalkanes to Nitroalkenes Catalyzed by<i> C</i>₂-Symmetric Tridentate Bis(oxazoline) and Bis(thiazoline) Zinc Complexes

Abstract

The first asymmetric synthesis of 1,3-dinitro compounds through Michael addition of nitroalkanes to nitroalkenes catalyzed by C2-symmetric chiral tridentate bis(oxazoline) and bis(thiazoline) zinc complexes was achieved with high enantioselectivities (up to 95% ee).
