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

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).

Construction of quaternary stereocenters by nickel-catalysis of asymmetric Michael reactions

Quaternary stereocenters were constructed with an enantio-selectivity of up to 91‰ ee under aerobic conditions and at ambient temperature in the Michael reaction of β-dicarbonyl compounds and methyl vinyl ketone with Ni(OAc)2·4H2O an
