A facile enantioselective addition of terminal 3-en-1-ynes to cyclic N-acyl trifluoromethyl ketimines is reported. In the presence of Zinc/BINOL complexes, a series of enynylated tertiary carbinamines were readily obtained in 90–97% yield with 70–97% enantiomeric excess in a single chemical operation under mild reaction conditions.

锌介导的3-en-1-ynes末端对环三氟甲基酮亚胺的对映选择性加成

据报道，在环N-酰基三氟甲基酮亚胺中容易地对末端3-烯-1-炔进行对映选择性加成。在锌/ BINOL复合物的存在下，在温和的反应条件下，一次化学操作即可轻松获得一系列烯化的叔卡宾胺，产率为90-97％，对映体过量为70-97％。
