Manifold products: The enantioselective decarboxylative Mannich‐type reaction of cyanoacetic acid with N‐ (2‐pyridinesulfonyl)imines catalyzed by chiral 1,3‐bis(imidazolin‐2‐yl)benzene (Phebim)–PdII complexes afforded products with good enantioselectivity (see scheme). The reaction was applied to a wide range of imines with good yield and enantioselectivity. The obtained products can be converted into

亚胺的对映选择性
脱羧曼尼希型反应,提供的产物具有良好的对映选择性(请参阅方案)。该反应以良好的收率和对映选择性适用于各种
亚胺。所获得的产物可以被转化成各种化合物而不会损失对映体纯度。
