  用于快速灵活合成 1,3-多元醇的催化不对称迭代/多米诺醛交叉羟醛反应

  摘要：

  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。

  Hydroxyl-Directed Intermolecular Ketone-Olefin Couplings Promoted by SmI2

  摘要：

  SmI2-promoted intermolecular ketone-olefin couplings are facilitated and stereocontrolled by hydroxyl groups incorporated within the starting materials. For example, the SmI2-induced ketone - olefin coupling reactions of alpha-hydroxy ketone 5 with ethyl acrylate, acrylonitrile, ethyl crotonate, and 2(5 H)-furanone proceeded with high stereocontrol to afford the syn-1,2-diol products 6-9 in good yields. Excellent diastereoselectivity was achieved in the reductive couplings of beta-hydroxy aldehyde 21 and erythro-beta-hydroxy ketone 24 with acrylonitrile using SmI2, to produce the anti-1,3-diols 22 and 25 in good yields. The sense of the stereo-selectivity was in full accord with a chelation-control model. In the proposed model, the stereochemistry of the reaction product is explained by assuming that a cyclic ketyl radical is generated during the initial single-electron reduction by SmI2. This radical species results from the chelation of the Sm-III cation, attached to the ketyl radical, with the hydroxyl group.

  anti-Selective synthesis of aldols with quaternary carbon centers was achieved by germanium(II)-mediated reductive cross-aldol reaction of tertiary α-bromo aldehydes with both aromatic and aliphatic aldehydes. One-pot direct reduction and reductive amination of the aldol products were performed to give the corresponding 1,3-diol and 1,3-amino alcohol with stereocontrolled quaternary carbon centers

  An organocatalyst for oxidizing alcohols in which a primary alcohol is selectively oxidized in a polyol substrate having a plurality of alcohols under environmentally-friendly conditions. The organic oxidation catalyst has an oxygen atom bonded to a nitrogen atom of an azanoradamantane skeleton and at least one alkyl group at positions 1 and 5. The oxidation catalyst has higher activity than TEMPO, which is an existing oxidation catalyst, in the selective oxidation reaction of primary alcohols, and better selectivity than AZADO and 1-Me-AZADO. This DMN-AZADO can be applied to the selective oxidation reaction of primary alcohols that contributes to shortening the synthesizing process for pharmaceuticals, pharmaceutical raw materials, agricultural chemicals, cosmetics, organic materials, and other such high value-added organic compounds.
