forming reactions, such as aldol reaction and condensation, belong to extremely desired transformations as manifested by >25,000 entries in SciFinder. Their stereoselective variant requires the use of an appropriate catalyst with a strictly defined structure. Hence, chiral 2-azabicycloalkane-based catalysts were designed, synthesized and tested in a stereoselective aldol reaction between cyclic/acyclic
碳-碳键形成反应,如羟醛反应和缩合,属于非常需要的转化,如 SciFinder 中 >25,000 个条目所证明的那样。它们的立体选择性变体需要使用具有严格限定结构的合适催化剂。因此,设计、合成了手性 2-氮杂双环烷烃基催化剂,并在有机和水介质中环状/无环酮和对硝基苯甲醛之间的立体选择性羟醛反应中进行了测试。在含有手性双环骨架的催化剂中,基于 2-氮杂双环 [3.2.1] 辛烷和吡咯烷单元的酰胺表现出最好的催化活性,并以优异的化学产率(高达 95%)和良好的非对映选择性和对映选择性提供了羟醛产物(博士22:78,EE 高达 63%)。
