Chaetoglobosins, Cytotoxic 10-(Indol-3-yl)-[13] cytochalasans from Chaetomium spp. III. Structures of Chaetoglobosins C, E, F, G, and J

Abstract

The structures (Chart 1) of chaetoglobosins C, E, F, G, and J, 10-(indol-3-yl)-[13] cytochalasans, were established on the basis of physical data, especially ¹H-NMR, and chemical correlations. The stereo-structural features of chaetoglobosins are discussed.
