Organocatalytic enantioselective allylic alkylation of MBH carbonates with β-keto esters

Org Biomol Chem. 2014 Jul 28;12(28):5071-6. doi: 10.1039/c4ob00682h.

Abstract

The highly stereoselective allylic alkylation of Morita-Baylis-Hillman carbonates with β-ketoesters catalysed by β-ICD is described. The corresponding products containing two adjacent quaternary and tertiary carbon centers were obtained in good yields with high diastereoselectivity (up to 10 : 1 dr) and enantioselectivity (up to 95% ee).
