SYNTHESES OF THIENOMORPHAN, THIENOMORPHAN AND 3-THIAMORPHINAN DERIVATIVES

Thienomorphans (4-7), (27) and (28) were prepared by cyclization of 2-thenyl-4-hydroxypiperidines (3) or 2-thenyltetrahydropyridine (26) with hydrobromic acid.Thienomorphans (37) and (38) and 3-thiamorphinan (47) were similarly prepared.Some
