Alstonia undulata

A,a-Methyl-16-epipericyclivine [16-De(hydroxymethyl)voachalotine] Alstonia undulata... [Pg.111]

Alstonia sphaerocapitata and A. undulata provided undulatine (315) and deformylundulatine (316), respectively (213(214). The alkaloids are constituted from the union of a cabucraline unit and a N-methylpericyclivine unit, via C(10) of the former to C(6 ) of the latter. The structures were elucidated on the basis of mass spectral and NMR data (213). An undulatine-type bisindole 317 has been prepared via acid-mediated coupling of a pericyclivine derivative 318 with the electron-rich cabucraline (319) (215). [Pg.230]
