  Isolation and total syntheses of two new alkaloids, dubiusamines-A, and -B, from Pandanus dubius

  摘要：

  Chemical investigation of the crude base of Pandanus dubius led to the isolation of two new alkaloids, dubiusamine-A (1) and dubiusamine-B (2). The structures of the two alkaloids including their absolute configuration were unambiguously confirmed by 1D and 2D NMR analysis and asymmetric total synthesis. (C) 2010 Elsevier Ltd.
