Indole alkaloids from Gelsemium elegans

Phytochemistry, 2019
Five previously undescribed monoterpenoid indole alkaloids were isolated from the roots of Gelsemium elegans. Their structures with absolute configurations were elucidated by HRESIMS, X-ray diffraction, ECD spectra, and molecular modeling. 19,20-Epoxyhumantenine is a humantenine-type alkaloid with an epoxypropyl group at the C-20 position, (4R)-19-oxo ...

Indole alkaloids from Ervatamia chinensis

Phytochemistry, 2012
Four vobasinyl-ibogan type bisindole alkaloids, ervachinines A-D (1-4), along with 12 known terpenoid indole alkaloids, were isolated from the whole plant of Ervatamia chinensis. Their structures were elucidated by analysis of spectroscopic data, including 1D and 2D NMR, and the absolute configurations of 1-4 were determined by CD exciton chirality ...

Indole Prenylation in Alkaloid Synthesis

2011
Important biologically active indole alkaloids are decorated with prenyl (3,3-dimethylallyl) and tert-prenyl (1,1-dimethylallyl) groups. Covering the literature until the end of 2010, this review article comprehensively summarises and discusses the currently available technologies of prenylation and tert-prenylation of indoles, which have been applied ...
