  Chiral Primary Amine Organocatalysts for Syn-selective Asymmetric Cross-Aldol Reactions

  摘要：

  Based on the "acid-base" interaction strategy, organocatalysts for the asymmetric cross-aldol reaction were synthesized by the in situ combination of chiral primary amines with protonic acids. Unlike general secondary amine catalysts that give anti-selective products, as-prepared primary amine catalysts can give syn-selcctive cross-aldol products with high yield and high selectivity (up to 90% yield, 90:10 syn/anti ratio, 90% ee). Compared with the complex synthesis of the reported catalysts, the primary amine catalyst that gave the best results was easily prepared using commercial available (1S,2S)-(+)-cyclohexanediamine.

  aldehydes and stereoselectivity can be flexibly switched in a stepwise manner for the double-aldol reaction. Furthermore, asymmetric triple- and quadruple-aldol reactions are possible in one-pot using the appropriate amounts of donors and amine additives, rapidly elongating the carbon skeleton with controlling up to eight stereocenters. The method should be useful for straightforward synthesis of enantiomerically

  我们在这里报告了醛之间的催化不对称迭代和多米诺交叉羟醛反应，具有高度的稳健性、灵活性和通用性。Cu(I)-DTBM-SEGPHOS 复合物催化受体醛和由供体醛衍生的硼烯醇化物之间的不对称交叉羟醛反应，该反应是通过 Ir 催化的烯丙氧基硼酸酯异构化产生的。可以重复使用醛醇产物作为随后不对称醛醇反应的受体底物的单元过程。双醇醛反应的供体醛和立体选择性可以以逐步的方式灵活切换。此外，使用适量的供体和胺添加剂，可以在一锅法中进行不对称的三重和四重醛醇反应，通过控制多达八个立体中心快速拉长碳骨架。该方法可用于直接合成对映异构和非对映异构富集的 1,3-多元醇。

  Highly syn-selective cross-aldol reaction of aldehydes has remained a challenging subject in the field of aminocatalysis. To achieve this end, chiral primary amines have been explored and the primary−tertiary diamine−Brønsted acid salts are found to promote the cross-aldol reactions of aldehydes with high activity and syn selectivity. Among various vicinal diamines screened, l-phenylalanine derived

  在氨基催化领域，醛的高度顺-选择性交叉-羟醛反应一直是具有挑战性的主题。为了达到这个目的，已经研究了手性伯胺，发现伯叔叔二胺布朗斯台德酸盐可以高活性和顺选择性地促进醛的交叉羟醛反应。在筛选的各种邻位二胺中，1-苯丙氨酸衍生的2a / TfOH共轭物被确定为最佳催化剂，显示出良好的催化活性（高达97％的产率）和高的合成选择性（syn / anti高达24：1、87％ee） 。当前的催化选择性地与较小的脂族醛供体（例如丙醛和异丁醛）一起起作用，但不适用于带有较大β-取代基（> Me）的脂族醛。另外，使用2a / TfOH共轭物也使糖醛供体的第一个顺-选择性交叉-羟醛反应成为可能。
