Paratunamides A-D, oxindole alkaloids from Cinnamodendron axillare

J Nat Prod. 2006 Oct;69(10):1517-21. doi: 10.1021/np0602968.

Abstract

Four new oxindole alkaloids, paratunamides A-D (1-4), containing a secologanin unit, were isolated from the bark of Cinnamodendron axillare, and their structures and relative configurations were elucidated by spectroscopic data. The absolute configuration at C-7 in 1-4 was assigned as S, S, R, and S, respectively, on the basis of the CD spectra.
