On the synthesis of pyrinodemin A. Part 1: The location of the olefin
摘要:
The elucidation of the structure of the cytotoxic marine sponge alkaloid pyrinodemin A by synthesis is described. Based on the C-13 NMR spectra of three double bond positional isomers and the natural product, it is concluded the C14'-C15' isomer best represents the true structure of pyrinodemin A. In addition, the structural assignment of pyrinodemin C is evaluated. (C) 2004 Elsevier Ltd. All rights reserved.
