Organocatalytic asymmetric Michael/hemiketalization/acyl transfer reaction of 1,3-propanediones with (E)-2-(2-nitrovinyl)phenols

Abstract

An organocatalytic asymmetric cascade Michael/hemiketalization/acyl transfer reaction between (E)-2-(2-nitrovinyl)phenols and 1,3-propanediones is disclosed. A cinchona alkaloid derived bifunctional thiourea catalyst was found to be the most effective for this reaction and provided the desired products in moderate to good yields with good to high enantioselectivities.
