  Synthesis of Versatile Bifunctional Derivatives of Chiral Diamines Obtained through Anchimerically Assisted Nucleophilic Substitution Reactions on Diastereomeric Phenylprolinols

  摘要：

  Diastereomeric [(S)-1-benzylpyrrolidin-2-yl]-(R)-[(phenyl)methanamine] and [(S)-1-benzylpyrrolidin-2-yl]-(S)-[(phenyl)methanamine], were synthesized by selective internal backside nucleophilic substitution of the corresponding activated phenylprolinols. X-Ray diffraction structures of crystalline acetamide derivatives confirmed the anticipated stereochemistry for a S(N)ib reaction mechanism. In order to apply this reaction to the synthesis of bifunctional analogs, a series of fragments such as a thiourea moiety and sulfonamide functions were introduced for the functionalization of the primary amino group in the substrate, obtaining more stable and potentially useful derivatives.

  C6构型在l-脯氨酸衍生的双功能有机催化剂催化活性中的作用

  摘要：

  合成了1-脯氨酸衍生的手性双官能（硫）脲有机催化剂epi - PTU和epi - PU，并将它们的催化性能与C6差向异构催化剂PTU和PU在硝基苯乙烯的各种迈克尔反应中进行了反应性和立体选择性方面的比较。实验结果表明，1-脯氨酸衍生的双官能有机催化剂在C2和C6处的适当相对立体化学对于成功催化非常重要，并且具有2 S，6 R的催化剂（PTU和PU） 配置效率更高。

• New class of bifunctional thioureas from l-proline: highly enantioselective Michael addition of 1,3-dicarbonyls to nitroolefins

  日期：2014.4

  A new class of bifunctional tertiary amine thiourea was synthesized from L-proline. The reported thiourea is amenable to steric and electronic modifications at the stereogenic center bearing a thiourea moiety. Excellent enantioselectivity was obtained in the Michael addition of 2,4-pentanedione to various nitro olefins using the new organocatalyst. The construction of contiguous stereocenters via the Michael reaction of substituted 1,3-dicarbonyls to nitro olefins was also carried out with very good yield, enantioselectivity, and diastereoselectivity.

  chiral bifunctional (thio)urea organocatalysts epi-PTU and epi-PU were newly synthesized, and their catalytic performances were compared with their C6 epimeric catalysts PTU and PU in various Michael reactions of nitrostyrene in terms of reactivities and stereoselectivities. The experimental results indicate that a proper relative stereochemistry at C2 and C6 in l-proline-derived bifunctional organocatalysts
