  • SN2 reaction of 2-substituted 3-piperidinol mesylate with retention of configuration: application to the asymmetric synthesis of (2R,3S)-CP-99,994
    作者:Liang-Xian Liu、Pei-Qiang Huang
    DOI:10.1016/j.tetasy.2006.12.009
    日期:2006.12
    Starting from protected (S)-3-hydroxyglutarimide 2a, the asymmetric synthesis of (2R,3S)-CP-99,994 8 was achieved. The crucial steps were a neighboring group participation leading to pyrrolidino-aziridinium intermediate 25 and the subsequent regioselective ring-opening reaction. In the case where neighboring group participation was not involved, only the eliminated product 15 was obtained.
    从受保护的(S)-3-羟基戊二酰亚胺2a开始,实现了(2 R,3 S)-CP-99,994 8的不对称合成。关键步骤是导致邻吡咯烷基-叠氮鎓中间体25和随后的区域选择性开环反应的邻近基团参与。在不涉及邻组参与的情况下,仅获得淘汰产品15。
  • A General and Simple Diastereoselective Reduction by L-Selectride: Efficient Synthesis of Protected (4S,5S)-Dihydroxy Amides

    A general approach to (4S,5S)-4-benzyloxy-5-hydroxy-N-(4-methoxybenzyl) amides 10 based on a diastereoselective reduction of (5S,6RS)-6-alkyl-5-benzyloxy-6-hydroxy-2-piperidinones 6 and their tautomeric ring-opened keto amides 7 is described. The reduction with L-Selectride at -20 °C to room temperature afforded the products 10 in excellent yields and moderate to high syn-diastereoselectivities.
    本文介绍了一种基于非对映选择性还原 (5S,6RS)-6-烷基-5-苄氧基-6-羟基-2-哌啶酮 6 及其同分异构体开环酮酰胺 7 的 (4S,5S)-4-苄氧基-5-羟基-N-(4-甲氧基苄基)酰胺 10 的一般方法。在 -20 °C 至室温条件下,用 L-选择性氮化物进行还原,得到了产率极佳、具有中等至高同-非对映选择性的产物 10。
  • Chemo- and diastereoselective control for a flexible approach to (5S,6S)-6-alkyl-5-benzyloxy-2-piperidinones
    作者:Liang-Xian Liu、Kai-Jiong Xiao、Pei-Qiang Huang
    DOI:10.1016/j.tet.2009.03.021
    日期:2009.5
    Chemo- and diastereoselective transformation of the N,O-acetals and their chain tautomers (4/5), readily derived from protected 3-hydroxyglutamide 1a, Was Studied. It Was Uncovered that while the reaction with a combination of boron trifluoride etherate/zinc borohydride led to cyclic products (5S,6S/R)-6-alkyl-5-benzyloxy-2-piperidinones 3/2, and 6 in modest chemo- and diastereoselectivities, the reaction of 4/5 with zinc borohydride led exclusively to the formation of the ring-opening products 6 in excellent anti-diastereoselectivities. On the basis of the latter reaction, a flexible approach to (5S,6S)-6-alkyl-5-benzyloxy-2-piperidinones 3 was disclosed. (C) 2009 Elsevier Ltd. All rights reserved.

    A general approach to (5S,6R)-6-alkyl-5-benzyloxy-2-piperidinones based on the regio- and diastereoselective reductive alkylation of (S)-3-benzyloxyglutarimide 7 is described. This method opens an entrance to chiral nonracemic substituted 3-piperidinols. The versatility of the method is illustrated by the asymmetric syntheses of neurokinin substance P receptor antagonist L-733,061 (ent-1), ()-deoxocassine
