Abstract

Abstract The conjugate addition of organolithium reagent to α, β-unsaturated ketone has been accomplished with methylaluminum bis (2, 6-di-tert-butyl-4-alkylphenoxide)(MAD and MAT). Here combination of alkyllithium and MAD (or MAT) constitutes an amphiphilic system that allows to exhibit unusual selectivity in the alkylation of enones with alkyllithium.
