  Application of the chiral base desymmetrisation of imides to the synthesis of the alkaloid jamtine and the antidepressant paroxetine

  摘要：

  The synthesis of the alkaloid jamtine and the antidepressant paroxetine have been addressed by a strategy involving asymmetric desymmetrisation of prochiral imides by a chiral lithium amide base. A short reaction sequence, starting with a cyclohexane fused succinimide, led to the structures originally reported for the alkaloid jamine and its derived N-oxide. The structures synthesised are shown not to correspond with those originally reported. A second sequence involves desymmetrisation of a 4-arylglutarimide, and provides a short enantioselective synthesis of the drug substance paroxetine. (C) 2003 Elsevier Ltd. All rights reserved.

  Enantioselective Desymmetrization of Glutarimides Catalyzed by Oxazaborolidines Derived from cis-1-Amino-indan-2-ol

  摘要：

  Enantioselective reductive desymmetrization of glutarimides,has been achieved employing an oxazaborolidine catalyst derived from cis-1-amino-indan-2-ol. The reaction was found to proceed through a stereoablative process, that upgraded the enantioselectivity of an intermediate,hydroxy-lactam. The reaction: was generally tolerant of a number of substituents in the 4-position giving enantiomeric excesses of greater than 82%.

• A Novel Chiral Base Mediated Glutarimide Desymmetrisation: Application to the Asymmetric Synthesis of (-)-Paroxetine

  日期：——

  The asymmetric desymmetrisation of certain 4-aryl substituted glutarimides has been accomplished with high levels of selectivity (up to 97% ee) by enolisation with a chiral bis-lithium amide base. The selectivity of the reaction is shown to be the result of asymmetric enolisation, followed by a kinetic resolution. One of the chiral imides synthesised was converted into the selective seratonin reuptake inhibitor (-)-paroxetine.

  This work represents the first catalytic hydrogenation of imides into amides and primary alcohols, in which the unique chemoselectivity is originated from the bifunctional nature of ruthenium-NH moiety in the catalyst.

  这项工作代表了第一次将酰亚胺催化氢化成酰胺和伯醇，其中独特的化学选择性源于催化剂中钌-NH 部分的双功能性质。
