Quinolizidines. XXII. An Extension of the "3-Acetylpyridine Route" to the Syntheses of 9-Hydroxy-10-methoxy- and 10-Hydroxy-9-methoxybenzoquinolizidine-Type Alangium Alkaloids

Alternative syntheses of the Alangium alkaloids bearing the 9-hydroxy-10-methoxy- and 10-hydroxy-9-methoxybenzoquinolizidine skeletons (types 3 and 4) have now become feasible through generally applicable routes starting from 3-acetylpyridine.The route

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
