STUDIES IN BIOMIMETIC ALKALOID SYNTHESES-10. THE SYNTHESYS OF A 19-OXOSECODINE AND ITS CYCLIZATION TO MINOVINCINE

The synthesis, isolation and characterization of 19-oxo Δ20,21 secodine (2) is described.This compound is first example of a stabilized, potentially reactive secodine intermediate in alkaloid synthesis.It cyclized to minovincine (1) in 77 perce

Synthesis of vinca alkaloids and related compounds. Part 102: Simple synthesis and ring transformation of (±)-minovincine. First synthesis of (±)-vincaminine

A molecule with an indole skeleton, containing a latent acrylic ester function - acting as a diene - readily reacted with benzoic acid (4-bromomethylene-5-oxo)hexyl ester that had been built up from pentane-2,4-dione. Dehydration of the enamine and subseq

Synthesis of Vinca Alkaloids and Related Compounds. 90.1 New Results in the Synthesis of Alkaloids with the Aspidospermane Skeleton. First Total Synthesis of (±)-3-Oxominovincine

The tryptamine derivative 1 readily reacted with methyl 4-acetyl-5-bromopent-4-enoate (9) that had been built up from 2,4-pentanedione. On intramolecular dehydration and subsequent [4 + 2] cycloaddition, the reaction product 10 gave the epimers 12 and 13 having the D-secoaspidospermane skeleton. Compound 12 directly and 13 after epimerization yielded (±)-3-oxominovincine (14). Regioselective reduction of 14 furnished (±)-minovincine (17).
