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

SYNTHESES OF (-)-9-DEMETHYLCEPHAELINE AND (-)-10-DEMETHYLCEPHAELINE

The synthesis of (-)-9-demethylcephaeline (I) has been accomplished by reduction of (+)-O,O-dibenzyl-8-demethylpsychotrine (XIa) followed by debenzylation of the resulting (-)-tetrahydroisoquinoline derivative XIIa.A parallel synthesis starting with (+)-O
