strongly on the use of o-alkoxy (or o-fluoro) aniline-derived aldimines which have been found to have a potential effect on the enolate addition. This scope was expanded to the asymmetric process using the chiral acetate. A Lewis acid additive has a complementary role in the pronounced activation of imine functionalities.
我们在这里介绍一种策略,该策略可以将
乙酸烯醇
锂有效地添加到
亚胺中。新方法在很大程度上取决于使用邻烷氧基(或邻
氟)
苯胺衍生的醛
亚胺,已发现其对烯醇盐的添加有潜在影响。使用手性
乙酸酯将这一范围扩展到不对称过程。
路易斯酸添加剂在
亚胺官能团的明显活化中具有互补作用。
