Thebaine-hydroquinone

Thebaine-hydroquinone is a very weak base the salts of which are largoly hydrolysed in solution it is recovered as the baso on rocrys-tallization from acotio acid [2], The two hydroxyl groups differ in... [Pg.291]

When thebaine-hydroquinone is heated with glacial acetic acid and concentrated hydrochloric acid [2, 4] or with 50 per cent, sulphuric acid [4] profound rearrangement of the molecule occurs, and a new base, flavothebaone , is obtained. [Pg.293]

Applying the mechanism (6) for the thebaine -> morphothebaine rearrangement to the transformation of thebaine-hydroquinone to flavothebaone we have the following ... [Pg.296]

Demethylation of flavothebaone with hydrobromic acid gives 0-desmethylflavothebaone [li], also obtained by heating thebaine-hydroquinone with concentrated hydrobromic acid [2]. [Pg.300]
