Stereodivergent Pd/Cu catalysis: asymmetric alkylation of racemic symmetrical 1,3-diphenyl allyl acetates

Org Biomol Chem. 2021 Mar 11;19(9):1955-1959. doi: 10.1039/d0ob02499f.

Abstract

We report a stereodivergent Pd/Cu catalyst system that was successfully applied to the asymmetric allylic alkylation of symmetrical 1,3-disubstituted allyl acetates with prochiral imino esters, providing efficient access to enantiopure products bearing vicinal stereocenters in a fully stereodivergent manner. The protocol proceeds smoothly under mild reaction conditions and can accommodate a range of imino esters, delivering the substituted products in high yields and with excellent diastereoselectivities (up to >20 : 1 dr) and enantioselectivities (up to >99% ee).
