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

Quinolizidines. XII. Synthetic Incorporation of Ethyl Cincholoiponate into a Tricyclic Intermediate Adaptable to Chiral Syntheses of the 10-Hydroxy-9-methoxybenzoquinolizidine-Type Alangium Alkaloids

For the purpose of securing a key intermediate for chiral syntheses of the 10-hydroxy-9-methoxybenzoquinolizidine-type Alangium alkaloids (type 4), the tricyclic ester (-)-15 has been synthesized from ethyl cincholoiponate and 4-benzyloxy-3-met

CONVERSION OF ETHYL CINCHOLOIPONATE INTO A TRICYCLIC INTERMEDIATE ADAPTABLE TO CHIRAL SYNTHESES OF 10-DEMETHYLATED ALANGIUM ALKALOIDS

The title (-)-tricyclic amino ester VII has been synthesized by means of an initial condensation of 4-benzyloxy-3-methoxyphenacyl bromide with (+)-ethyl cincholoiponate (VIII), derived from the Cinchona alkaloid cinchonine, and succeeding steps proceeding
