Studies in terpenoid biosynthesis. Part 31. Some aspects of the chemistry and biosynthesis of the steroidal antibiotic, demethoxyviridin
Abstract
The stereochemistry of some reactions of demethoxyviridin including the reduction of ring A and the preparation of deuteriated dehydroxydemethoxyviridin, is described. The detection of the latter in the fungus, Nodulisporium hinnuleum and its conversion into demethoxyviridin, is reported.
