Unexpected oxidation of ortho-phenol groups of carnosol with m-chloroperbenzoic acid

The oxidation reaction of carnosol (2) with m-chloroperbenzoic acid and sodium bicarbonate in dichloromethane gave an abietane diterpene (3) with an anhydride function on C ring. The conversion can be rationalized by a Baeyer-Villiger reaction from the initially generated ortho-quinone. The structure of this anhydride was confirmed by spectroscopic and X-ray crystallographic analysis. This reaction could be an important key step towards the synthesis of natural products such us drimane sesquiterpenes.
