Get asymmetric! Asymmetric [4+1] annulation of sulfur ylides and N-(ortho-chloromethyl)aryl amides allowed the formation of the desired cycloadduct with moderate to high yields and enantioselectivities (see scheme). The described strategy, taking advantage of chiral sulfur ylides, represents a direct procedure to access chiral 2-substituted indolines.
获得不对称性!硫叶立德和 N-(邻氯甲基)芳酰胺的不对称 [4+1] 环加成反应以中等至较高的收率和对映选择性形成所需的环加成产物(见方案)。所描述的策略利用手性硫叶立德,代表了一种直接获得手性 2-取代吲哚啉的方法。
