    Nucleophilic substitution on α-mesyloxy-O-alkyloximes—I. Enantiospecific synthesis of 2-(imidazol-1-yl)-1,3-diphenylpropan-1-one O-alkyloximes
    摘要:
    An enantiospecific synthesis of (S)- and (R)-(E)-5-[1,3-diphenyl-2-(imidazol-l-yl)propylidene] aminooxypentanoic acids 1 using homochiral phenylalanines as starting material is described. Chiral alpha-hydroxyketones 9 were obtained from alpha-hydroxyacids 7 by Weinreb's ketone synthesis. Imidazole introduction by nucleophilic substitution on mesylate 10 led to 2-(imidazol-1-yl)propan-1-one derivative 3, key intermediate in the synthesis of 1. However, the low configurational stability displayed by compound 3 compromised its use in an enantiospecific synthesis. Homochiral compounds 1 were then obtained by a nucleophilic substitution on alpha-mesyloxy-O-alkyloxymes 14 which were in turn obtained from 9. This nucleophilic substitution on alpha-mesyloxy-O-alkyloxymes was not previously reported either on homochiral compounds or on racemic derivatives. (C) 1997 Elsevier Science Ltd.

  • Rearrangement of <i>N</i>-<i>tert</i>-Butanesulfinyl Enamines for Synthesis of Enantioenriched α-Hydroxy Ketone Derivatives
    作者:Chun-Tian Li、Hui Liu、Yun Yao、Chong-Dao Lu

    日期:2019.10.18
    hexamethyldisilazide (or potassium tert-butoxide) and methyl triflate gives N-methylated N-tert-butanesulfinyl enamine intermediates that undergo stereoselective [2,3]-rearrangement to afford α-sulfenyloxy ketones with excellent enantiopurities. This cascade of enamination-N-methylation-rearrangement was even used to generate acyclic tertiary α-hydroxy ketones bearing two α-substituents showing negligible
    用六甲基二硅叠氮化钾(或叔丁醇钾)和三氟甲磺酸甲酯处理手性N-叔丁烷亚砜基酮亚胺,可得到N-甲基化的N-叔丁烷亚砜基烯胺中间体,该中间体经立体选择性[2,3]重排可制得具有优异α-亚磺酰氧基酮的化合物对映体。这种级联的N-甲基化重排反应甚至被用于生成带有两个α-取代基的无环叔α-羟基酮,这些α-取代基的体积差异可忽略不计,例如甲基和乙基。

    日期:2021.2.19
    A catalytic enantioselective acyloin rearrangement of acyclic aldehydes to synthesize highly optically active acyloin derivatives is described. In the presence of a chiral oxazaborolidinium ion catalyst, the reaction provided chiral α-hydroxy aryl ketones in high yield (up to 95%) and enantioselectivity (up to 98% ee). In addition, the enantioselective acyloin rearrangement of α,α-dialkyl-α-siloxy
