  Semisynthesis of heterocyclic analogues of squamocin, a cytotoxic annonaceous acetogenin, by an unusual oxidative decarboxylation reaction

  摘要：

  In addition to two expected pyrazin derivatives, two imidazole analogues of squamocin I have been semisynthetised from squamocin derived alpha-ketoesters/alpha-ketoacid, via an unusual condensation-oxidative decarboxylation reaction with 1,2 diamines in presence of acetic acid and oxygen as the key step. Some of these analogues exhibited potent, although significantly reduced cytotoxicities relatively to squamocin 1. In addition, benzimidazole 8 possessed in comparison with the natural acetogenin some interesting cell cycle effects. (C) 2003 Elsevier Ltd. All rights reserved.
