Asymmetric Baylis-Hillman reaction: Use of novel chiral aldehydes as electrophiles, chiral base catalysts and auxilliaries

摘要

The present review highlights Our recent research findings in the field of asymmetric Baylis-Hillman reaction. in particular, it elaborates oil the following efficient aids: 1) utilization of sugar-derived acrylates as chiral auxiliary for diastercoselective Baylis-Hillman reaction; 2) use of novel chiral electrophiles such as sugar-derived aldehydes and chiral 2,3-epoxy aldehydes for the diastereoselective Baylis-Hillman reaction to obtain valuable chiral adducts 3) a novel prolinol derivative promoted enantioselective Baylis-Hillman reaction and intramolecular Baylis-Hillman reaction wherein both the aldehyde and acrylate component Structure of the same molecular framework to afford high de 's. This review also covers the related research work from other groups on asymmetric Baylis-Hillman reaction.
