    摘要:
    Three new indole alkaloids, 17-O-acetyl-N-b-demethylechitamine, echitamidine N-oxide and echitaminic acid, have been isolated from the stem bark of Alstonia glaucescens along with one iridoid compound, sweroside, and five known indole alkaloids, i.e. echitamidine, N-b-demethylechitamine, 20-epi-19 xi-echitamidine, N-b-demethylechitamine N-oxide and echitamine. Their structures were elucidated by spectroscopic methods, especially 2D NMR.

    general strategy for the synthesis of pentacyclic Strychnos alkaloids with the curan skeleton has been developed. It utilizes 3a-(2-nitrophenyl)hexahydroindol-4-one (23), which was prepared from 2-allyl-2-(2-nitrophenyl)-1,3-cyclohexanedione (15), as the common, pivotal intermediate. Three different procedures have been employed for the closure of the bridged piperidine D ring from 23: (i) an intramolecular

    Three new indole alkaloids, N(4)-demethyl-12-metboxyalstogustine (1), 17-carboxyl-N(4)-methylechitamidine chloride (2), and 17-carboxyl-12-niethoxy-N(4)-methylechitamidine chloride (3), along with 15 known alkaloids, were isolated from the ethanolic extract of the stem bark of Winchia calophylla. The structures of 1-3 were elucidated on the basis of spectroscopic means and chemical methods. The determination of relative configurations at C-19 and C-20 for 1-3 was aided by C-13 NMR spectroscopic data. The absolute configurations of alkaloids 1-3 were determined by direct comparison of their CD spectra with those of known alkaloids. All the alkaloids were tested in cytotoxic assays against P-388 and A-549 tumor cell lines, and only two of them showed weak activity against the A-549 cell line.

    Intramolecular Diels-Alder reactions, at two stages in the reaction sequence, provided total syntheses of the racemate of the hypotensive alkaloid echitamidine (8) and of its C-19,20 and C-20 epimers 9a and 9b.
