  A chiral pyrrolidine-pyrazole catalyst for the enantioselective Michael addition of carbonyls to nitroolefins

  摘要：

  An enantioselective Michael reaction of carbonyl compounds to nitroolefins has been accomplished using a novel chiral pyrrolidine-pyrazole catalyst. This newly prepared catalyst was found to be very effective in providing good yields as well as good diastereo- and enantio-selectivities. The mechanism of the reaction has also been substantiated by mass spectral studies. (C) 2011 Elsevier Ltd. All rights reserved.

  versatile catalysts in many reactions, l-prolinol was seldom used as organocatalyst for reactions. Herein, we report the first l-prolinol catalyzed asymmetric Michael addition of cyclohexanone to nitroolefins in the presence of benzoic acid to afford Michael adducts with high diastereoselectivities (87:13–>99:1) and enantioselectivities (82–96%).

  尽管已经证明许多手性胺例如1-脯氨酸及其衍生物在许多反应中是通用催化剂，但是1-脯氨醇很少用作反应的有机催化剂。在本文中，我们报道了第一升-prolinol催化不对称迈克尔加成的环己酮在苯甲酸的存在nitroolefins得到迈克尔加成物具有高非对映选择性（87：13-> 99：1）和对映选择性（82-96％）。

  A new pyrrolidine-triazole conjugate organocatalyst is synthesized using a Huisgen 1,3-dipolar cycloaddition reaction. The application of this catalyst in an asymmetric Michael addition and in an Aldol reaction is described, showing good catalytic activity. The reactions proceeded to give the products in good yield and in a highly selective manner. (C) 2008 Elsevier Ltd. All rights reserved.

  A new class of proline based organocatalysts 'pyrrolidine-oxyimides' were designed and synthesized from L-proline and hydroxyimides by employing a simple reaction protocol. These catalysts were found to be efficient in promoting asymmetric Michael additions of ketones to nitroolefins at room temperature. Good yields and high selectivities were obtained with catalyst 1a under additive-free conditions employing water as the reaction medium. (C) 2014 Elsevier Ltd. All rights reserved.

  A new analogue of the proline derived organocatalyst 'pyrrolidine-HOBt' has been designed and synthesized from L-prolinol and hydroxybenzotriazole (HOBt) employing a simple reaction protocol. The catalyst was found to be effective in promoting the asymmetric Michael addition of cyclohexanone to nitroolefins using water as the reaction medium. The reaction products gamma-nitrocarbonyls are obtained in good yields and stereoselectivities. (C) 2016 Elsevier Ltd. All rights reserved.
