Catalytic hydrogenation of the isomerc homoproaporphines (Va and Vb) and the deuterated dienones VIa and VIb in the presence of platinum afforded the same mixture of cyclohexanols (VIIa and VIIb). In contrast, palladium reduction of the hydrochloride of Va provided the cyclohexanone (VIIIa) while that of Vb gave a mixture of the cyclohexanone (VIIIb) and the cyclohexenone (IX).
