A useful Michael addition reaction using nitroalkanes as the nucleophile and 4-oxo-enoates as the Michael acceptor has been disclosed, and the reaction allows expedient access to functionalized chiral gamma-keto esters in high yields and excellent enantioselectivities (up to 98% ee), with a low catalyst loading.
已经公开了使用硝基烷作为亲核试剂和4-氧-烯酸酯作为迈克尔受体的有用的迈克尔加成反应,并且该反应允许以高收率和优异的对映选择性(高达98%ee)方便地获得官能化的手性γ-酮酯。 ,催化剂负载低。
