资源简介：
A direct catalytic asymmetric γ-regioselective vinylogous Michael addition of allyl alkyl ketones to maleimides has been developed through dienamine catalysis of a simple chiral 1,2-diphenylethanediamine, giving multifunctional products in excellent enantioselectivity and with high yields. The success of this catalytic strategy relies on the unique inducing effect of deconjugated β,γ-CC bond, which facilitates the formation of the otherwise unfavored extended dienamine species.
