  基于Epi- Cinchona的硫脲有机催化剂家族作为高效的不对称Michael加成促进剂：硝基链烷烃与查尔酮和α，β-不饱和N-酰基吡咯的对映选择性共轭加成

  摘要：

  A small set of easily available epi-cinchona based thiourea organocatalysts have been synthesized and tested in enantioselective Michael addition of nitroalkanes to chalcones. These bifunctional catalyst systems promoted the conjugate additions with high enantioselectivities and chemical yields. The extension of this methodology was further explored to encompass alpha,beta-unsaturated N-acylpyrroles, as a chalcone mimic. Functionally, the N-acylpyrrole moiety in the adduct acts as an ester surrogate; therefore, it can easily be transformed to various valuable and biologically relevant compounds. This approach allowed the concise stereoselective synthesis of (R)-rolipram.
