摘要
Asymmetric induction in the product of the Baylis-Hillman reaction between an aldehyde and an acrylic compound in the presence of a tertiary amine base, may be controlled by chirality in the aldehyde, acrylic ester, base or solvent; R-CHO + CH2 = CH-COOR' (B:, solvent) --> CH2 = C(C*HROH)-COOR' Examples of each are described but the best stereochemical result, 100% ee, is obtained from the high pressure reaction of benzaldehyde with (-)-menthyl acrylate.
