Abstract

AbstractAn organocatalytic asymmetric domino Michael/acyl transfer reaction between α‐nitroketones and o‐quinone methides is disclosed. o‐Quinone methides are generated in situ from 2‐sulfonylmethylphenols in basic medium. With 10 mol% of bifunctional squaramide catalyst, high yields and excellent enantioselectivities are achieved for a variety of O‐acyl 2‐(1‐arylethyl)phenols under mild reaction condition.magnified image
