Quinolizidines. X. Stereospecific Synthesis of (+/-)-9-Demethylpsychotrine and (+/-)-10-Demethylpsychotrine

With the aim of establishing the stucture of the Alangium alkaloid desmethylpsychotrine, stereospecific syntheses of two alternative structures, (+/-)-9-demethylpsychotrine (1) and (+/-)-10-demethylpsychotrine (2), have been achieved through a "lactim eth
