  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.

  A trans-piperidinedione of formula (1), where R is a benzyl group and R' is an optionally substituted C1-6-alkyl, aryl-C1-6-alkyl, C1-6-allyl or aryl group, which process comprises the reaction of a cinnamate ester of formula (3), where R'' has independently the same meaning as R', with a malonamide (4) in the presence of a strong base. Compound (2) is used in the presentation of paroxetine. The preparation of paroxetine by the route from compounds (3 and 4) avoids the formation of difficult to remove impurities found in other routes.
