available Boc-protected Z-alkenyl aminals could be used as Z-alkenyl and E-alkenyl imine precursors under acidic conditions. In the Mukaiyama–Mannich reaction of Z-alkenyl Boc-aminals, the E/Z geometry of the products was controlled by the catalyst used. The present method was also applied to asymmetric Mukaiyama–Mannich reactions.
在酸性条件下,现成的Boc保护的Z-烯基

缩醛可以用作Z-烯基和E-烯基
亚胺的前体。在Z-烯基Boc-
缩醛的Mukaiyama-Mannich反应中,产物的E / Z几何形状受所用催化剂的控制。本方法也适用于不对称的Mukaiyama–Mannich反应。
