  Synthesis of marine oxylipin topsentolide A1 and its stereoisomers, and determination of the absolute configuration of the natural product

  摘要：

  Four possible stereoisomers of topsentolide A(1), a cytotoxic oxylipin against human solid tumor cell lines, were efficiently synthesized in a stereoselective manner in order to determine the stereochemistry of natural product. The absolute configuration of topsentolide A(1) was determined to be 8R,11R,12S by comparing NMR spectra and specific rotations of the synthetic isomers and the natural product. Cytotoxicity of the synthetic isomers was also examined. (C) 2015 Elsevier Ltd. All rights reserved.

  Two possible stereoisomers of topsentolide A(1), a cytotoxic oxylipin against human solid tumor cell lines, were prepared in order to determine the stereochemistry of natural product. That is, the enantiomer of topsentolide A(1), (85,115,12R)-isomer, and its diastereomer was efficiently synthesized in a stereoselective manner. The stereochemistry of topsentolide A(1) was determined to be 8R,11R,12S by comparing NMR spectra and specific rotations of the synthetic isomers and the natural product. (C) 2010 Elsevier Ltd.
