(5β,12S,19β)-2,3-Didehydro-7α-ethyl-8,20,21-trinoraspidospermidine-3-carboxylic acid methyl ester Chemical Properties,Uses,Production

Description

A recent reinvestigation of the alkaloids present in the leaves of Tabernanthe iboga and T. subsessilis has resulted in the isolation of two new bases, ibophyllidine and iboxyphylline (q.v.). Ibophyllidine has been obtained as a non-crystallizable solid having no definite melting point. It is dextrorotatory with a specific rotation of [cd D + 1340 (c 1.0, CHCI3) and gives an ultraviolet spectrum in EtOH consisting of absorption maxima at 227,302 and 333 nm. The structure has been deduced primarily from a study of the ultraviolet and NMR spectra.
