Abstract

The marine natural product flustramine C from the bryozoan Flustra foliacea was synthesized in five steps and 38% yield starting from N b-methyltryptamine. The key step is the biomimetic oxidation of the natural product deformylflustrabromine causing selective 1, 2- rearrangement of the inverse prenyl group. By 1H, 15N HMBC experiments, it is unambiguously shown that the reaction with t-BuOCl commences with chlorination of the ...
