QUINOLIZIDINES. XXIII. AN ALTERNATIVE SYNTHETIC ROUTE TO BENZOQUINOLIZIDINE-TYPE ALANGIUM ALKALOIDS FROM ETHYL CINCHOLOIPONATE

The trans lactam acid (+)-XX was isolated in good yield in the form of the 4-methoxybenzyl ester (+)-XXV from an equilibrated 66:34 mixture of the trans and cis isomers , which was obtained by thermal cis-trans isomerization of the cis

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
