- Abstract
The treatment of drevogenin P with isovaleryl chloride in pyridine gave an amorphous 3,12-di-O-isovaleryl-drevogenin P ( 4), which, on energetic acetylation, was converted into 3-O-isovaleryl-drevogenin A ( 5). This could be isolated in crystalline form and was converted through mild alkaline hydrolysis into drevogenin A. Hence drevogenin A could be classified as 11-O-acetyl-12-O-isovaleryl-drevogenin P. Indirectly, the structure of drevogenin B could be deduced to be most probably that of 11α-mono-O-acetyl-drevogenin P. Some details of the earlier given structures [1] are corrected here. Drevogenin D has an 11α-hydroxyl group.
