Unknown compounds, 2, 3, 9-(I) and 1, 2, 9-Trimethoxyoxoaporphine (Ia) were synthesized via Bischler-Napieralski reaction and Pschorr reaction. 1, 2, 10-Trimethoxyoxoaporphine (Ib) was prepared from the corresponding dehydroaporphine by oxidation with peracid. Since the physical properties of the compound are not consistent with the reported data, the structure proposed for a product which was obtained by cleavage reaction with sodium in liquid ammonia of dehydrothalicarpine may be uncorrect.
