  Highly anti-Selective Asymmetric Nitro-Mannich Reactions Catalyzed by Bifunctional Amine-Thiourea-Bearing Multiple Hydrogen-Bonding Donors

  摘要：

  Highly anti-selective and enantioselective nitro-Mannich reactions have been achieved for a broad spectrum of substrates catalyzed by chiral bifunctional multiple hydrogen-bonding-donor amine-thioureas. Multiple hydrogen-bonding donors play a significant role in accelerating reactions and improving yields, diastereoselectivities, and enantioselectivities.

  simultaneously acidify the urea and provide asymmetric induction in hydrogen-bond-catalyzed reactions. The utility of this new catalyst structure is demonstrated by the high selectivity provided in the aza-Henry reaction not only for aromatic N-Boc imine substrates but also for aliphatic imines for which enantioselective H-bonding catalysis has not previously been demonstrated.

  已经开发出一类新的有机催化剂，它结合了亚磺酰基作为脲或硫脲取代基。亚磺酰基同时用于酸化尿素并在氢键催化反应中提供不对称诱导。这种新催化剂结构的实用性通过 aza-Henry 反应提供的高选择性得到证明，不仅对芳香族 N-Boc 亚胺底物，而且对脂肪族亚胺（之前尚未证明对映选择性氢键催化）。

  during an enantioselective reaction, this work represents the first example of this phenomenon outside of a protein. A chiral, nonracemic BisAMidine (BAM) ligand was designed, synthesized, and complexed to the proton of a Brønsted acid. The resulting coordination compound catalyzed the production of enantioenriched product from the combination of a Schiff base and nitroalkane (the aza-Henry reaction). This

  尽管大自然长期以来一直能够使用质子（最普遍的路易斯酸）在对映选择性反应期间激活和定向底物，但这项工作代表了蛋白质之外这种现象的第一个例子。设计、合成了手性、非外消旋双脒 (BAM) 配体，并与布朗斯台德酸的质子络合。所得配位化合物催化席夫碱和硝基烷烃（氮杂-亨利反应）结合生成对映体富集的产物。这种特殊的反应也被认为是许多由酶催化的类似碳-碳键形成反应的模型（例如，曼尼希反应）。这一发现表明在不对称催化中使用离子氢键可能不仅比以前认为的更普遍，而且是一种可行的“

  A catalytic asymmetric nitro-Mannich (aza-Henry) reaction with rare earth metal/alkali metal heterobimetallic catalysts is described. A Yb/K heterobimetallic catalyst assembled by an amide-based ligand promoted the asymmetric nitro-Mannich reaction to afford enantioenriched anti-b-nitroamines in up to 86% ee. Facile reduction of the nitro functionality allowed for efficient access to optically active
