Efficient procedures based on the use of iodine for the aromatization of a series of terpenoids possessing diene and homoallylic or allylic alcohol functionalities are described. Different examples are reported as a proof-of-concept study. Furthermore, iodine also proved to mediate the dehydrogenation of testosterone.
Carvone-derived 2,3-epoxy alcohol derivatives rearrange with stereoselective formation of ring-contracted ketones. In contrast to previously described similar processes, the stereochemical result seems to be independent of epoxide configuration.
