  pyrrolidine catalyst as a custom-made amine-catalyst was developed for the enantio- and diastereo selective Michael reaction of nitroalkenes with carbonyl compounds. In particular, a peptide-like catalyst in which an α-amino acid is attached to the anthranilic acid skeleton induced the high stereoselectivity of the reaction with aldehydes. Studies of the reaction mechanism indicated that the catalyst exhibits

  A new class of structurally rigid tricyclic amphibian chiral catalyst was rationally designed based on the hexahydropyrrolo[2,3-b]indole skeleton as a new type of chemzyme. This new type of chemzyme possesses a structurally rigid tricyclic skeleton and a chiral pocket which provides a well-organized chiral environment for asymmetric induction, as well as a hydrophobic pocket to enable organocatalytic

  作者：Dan Xu、Junliang Wang、Lijun Yan、Mingquan Yuan、Xiaotian Xie、Yongchao Wang

  日期：2016.12

  A series of novel bifunctional L-prolinamide derivatives was synthesised, of which (S)-N-((S)-2-oxo-1-phenyl-2-(tritylamino)ethyl)pyrrolidine-2-carboxamide 6 was found to be the most effective catalyst in terms of both the yield and stereoselectivity for the nitro-Michael reaction of aldehydes to nitroalkenes. Under these optimized reaction conditions, 17 corresponding novel nitro-Michael addition adducts had high yields (up to 94%) and showed excellent diastereoselectivity (up to 99:1 dr) and enantioselectivity (up to 98 ee) under mild reaction conditions.
