An enantioselective three-component reaction of α-diazo ketones with alkenes and 1,3,5-triazines is reported, which leads to poly-functionalized chiral ketones with excellent enantioselectivity. This unprecedented metal carbene gem-dialkylation reaction features a cascade formal asymmetric allylation and aminomethylation process with concomitant construction of all-carbon quaternary stereocenters using
报道了 α-重氮酮与烯烃和 1,3,5-三嗪的对映选择性三组分反应,这导致了具有优异对映选择性的多官能化手性酮。这种前所未有的金属卡宾宝石二烷基化反应具有级联的形式不对称烯丙基化和氨甲基化过程,同时使用现成的材料构建全碳季立构中心。
