When thebaine is heated in concentrated hydrochloric acid with stannous chloride, two phenolic ketones of the empirical composition ClsHzlOaN are formed. The structure of one of these, the “true” thebainone (Formula I) s is evident from the fact that it can be hydrogenated to the same dihydrothebainone as is obtained from the catalytic hydrogenation of thebaineS4 The second of these phenolic ketones, metathebainone, for ...
