Regio- and stereo-specific allylic oxidation of germacrane-type sesquiterpene lactones with selenium dioxide and t-butyl hydroperoxide
Abstract
The regio- and stereo-specific allyic oxidation of the germacrane-type sesquiterpene lactones epitulipinolide (1), eupatoriopicrin acetonide (2), and the O-methanesulphonate (3) with SeO2 and t-butyl hydro-peroxide is discussed.
