An efficient method for the asymmetric synthesis of chiral diynylated carbinamines is described. The direct catalytic enantioselective addition of terminal 1,3-diynes to N-sulfonyl aldimines proceeded smoothly under mild reaction conditions to produce diynylated carbinamines in up to 98% yield and 99% ee.
描述了一种不对称合成手性二炔化羧胺的有效方法。在温和的反应条件下,将末端1,3-二炔直接催化对映选择性加成到N-磺酰基醛亚胺上可以顺利进行,从而以高达98%的收率和99%ee的产率生产二酰化的羧胺。
