  Asymmetric Total Synthesis of the Proposed Structure of the Medicinal Alkaloid Jamtine Using the Chiral Base Approach

  摘要：

  [GRAPHICS]A highly step-economic asymmetric synthesis of the tetracyclic structure assigned to the medicinal alkaloid jamtine has been accomplished using a chiral lithium amide base desymmetrization of a ring-fused imide. The structure synthesized appears to be different from that of the natural product originally reported.

  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.
