Tabemaemontana corymbosa

Toh-Seok K, Kooi-Mow S. Conodurine, conoduramine, and ervahanine derivatives from Tabemaemontana corymbosa. Phytochemistry 1992 63 625-629. [Pg.145]

Tabemaemontana corymbosa also provided several new bisindole alkaloids, conodiparines A-D (362-365) which are constituted from union of iboga and vobasinyl moieties [237]. The spectral data indicated that in conodiparines A (362) and C (364), the dimers are branched from C(3) of the vobasinyl unit to C(IO ) of the iboga unit whereas in conodiparines B (363) and D (365), the connection is from C(3) to C(12 ). The configuration of C( 19 ) in conodiparines A (362) and B (363) was determined to be 5 from examination of the carbon shifts of C(15 ) and C(2r) which corresponds to those of the iboga alkaloid heyneanine (345), exemplifying the 19(5) series in iboga alkaloids with a hydroxylethyl side chain [238]. [Pg.425]
