✦ Synopsis
Michael addition of the dienolate derived from 2-butenoic acid to 1,3-diphenylpropenone occurs through a 1,2-addition followed by a 13,31-sigmatropic rearrangement. oL,r-regioselectivity found for Michael addition to other styryl ketones depends on the s-ceric parameter of the substituents at the carbonyl group, in agreement with the same tandem additionrearrangement mechanism.
