Abstract

The asymmetric catalytic Michael reaction between isobutyraldehyde and nitroalkanes with chiral primary amine thiourea organocatalysts was described. In the presence of 10 mol % of 1-((1R,2R)-2-amino-1,2-diphenylethyl)-3-benzylthiourea, the desired products were achieved in excellent enantioselectivity (up to>99% ee) with up to 98% yield.
