摘要

The enantioselective introduction of electrophiles α to carbonyl groups is a central topic in asymmetric synthesis. Although asymmetric α-alkylations have been well developed, high enantioselectivity in α-arylation of ketones has only been achieved in a very limited number of cases. These involve arylation of trisubstituted enolates using binap–Pd complexes which gives non-epimerizable, tetrasubstituted ketones.[1, 2] However, this strategy cannot be ...
