• Novel Easily Recyclable Bifunctional Phosphonic Acid Carrying Tripeptides for the Stereoselective Michael Addition of Aldehydes with Nitroalkenes

  日期：2016.1.7

  A novel bifunctional organocatalyst library combining both aminocatalysis and phosphonic acid activation was used for the first time as an efficient tool for the stereoselective Michael addition of aldehydes with several aromatic nitroalkenes with good selectivities up to 95:5 dr and 93:7 er. Due to their high water solubility, the catalysts were easily recyclable and could be reused over several cycles

  日期：2006.8

  Direct catalytic enantio- and diastereoselective Michael addition reaction of aldehydes to nitrostyrenes is described using a series of recyclable chiral 2-trimethylsilanyloxy-methyl-pyrrolidine-based dendritic catalysts. Good yields (up to 82%), and high diastereoselectivities (up to syn/anti = 95/5) and enantioselectivities (up to 99% ee) have been obtained.

  日期：2004.8

  The direct Michael addition of aldehydes and ketones to nitroolefins, catalyzed by N-i-Pr-2,2′-bipyrrolidine, is described. The desired 1,4-adducts are obtained in excellent yields with enantioselectivities up to 95% ee and dr up to 95 : 5 of the syn aldehyde addition product. An unexpected inversion of diastereoselectivity was observed for the addition of α-hydroxy ketones to β-arylnitroolefins with

  描述了由Ni -Pr-2，2'-联吡咯烷催化的醛和酮直接迈克尔加成到硝基烯烃上。以优异的产率获得所需的1,4-加合物，其对映体选择性高达合成醛加成产物的95％ee和dr：95：5 。对于以高达98％ee的对映选择性将α-羟基酮添加到β-芳基硝基烯烃中，观察到了非预期的非对映选择性反转。在α-羟基酮的OH基和催化剂的叔氮之间形成内部氢键导致形成刚性的顺式烯胺中间体，这解释了预期的非对映选择性和非常高的ee。

  New N-alkyl-3,3'-bimorpholine derivatives (iPBM) were revealed to be efficient organocatalysts for the asymmetric direct Michael addition of aldehydes to nitroolefins and a vinyl sulfone. In these transformations using iPBM, 1,4-adducts were afforded in high yields, with good to high levels of diastereo- and enantioselectivity. The stereochemical outcome of the reaction could be explained by an acyclic
