versions of the aldol reaction, the enantioselective reaction between cyclic ketones and aldehydes constitutes a typical reaction model for the evaluation of novel organocatalysts. A multifunctional organocatalyst consisting of a prolinamide moiety, a gem diamine unit and a urea group was successfully employed in this asymmetric transformation. The products of the reaction between various ketones and aldehydes
在各种形式的醛醇缩合反应中,环状酮和醛之间的对映选择性反应构成了评价新型有机催化剂的典型反应模型。由脯氨酰胺部分,宝石二胺单元和脲基团组成的多功能有机催化剂已成功地用于这种不对称转化中。以高收率(高达98%),出色的非对映异构体(高达> 98:2 dr)和对映选择性(高达99%ee)获得了各种酮与醛之间的反应产物。
