Chiral β-iodo Morita-Baylis-Hillman (MBH) adducts are important versatile synthetic building blocks for many nat-ural products and drug molecules. By using a recently developed acyl transfer catalyst An-PIQ, the kinetic resolutions of a series of β-iodo MBH adducts were investigated, providing the recovered alcohols in good yields with high enantioselectivities (up to 99.9% ee) and good selectivity factors (S up to 165). This method overcomes the issue of low selectivity confronted in the kinetic resolution of aliphatic aldehyde-derived MBH adducts as secondly alcohols, and features mild reaction conditions, broad sub-strate scope, and easy scaling-up to gram scale.

Key words: β-iodo MBH adducts, nucleophilic catalysis, enantioselectivity, kinetic resolution
