Schischkiniin support studies: synthetic access to 1,1′-bisindoles

Chem. Commun., 2013
The first general synthetic approach to 1,1'-bisindoles is described. Two simultaneous, ambient temperature Mori-Ban reactions were used to effect bisindolization of several diallylated hydrazobenzenes with minimal cleavage of the N-N bond.

Palladium-Catalyzed Cascade Heck Cyclization To Access Bisindoles

Organic Letters, 2018
A novel strategy for intercepting the σ-alkylpalladium species generated via a Heck reaction, enabling a palladium-catalyzed cyclization of o-ethynylanilines, has been described. This direct and operationally simple protocol provided a fundamental platform to synthesize bisindoles with high efficiency, involving one C-N bond and two C-C bond formations.

New vobasinyl-ibogan type bisindole alkaloids from Tabernaemontana corymbosa

Fitoterapia, 2015
Ten vobasinyl-ibogan type bisindole alkaloids, including three new ones, tabercorines A-C (1-3), and a new natural product, 17-acetyl-tabernaecorymbosine A (4), were isolated from the twigs and leaves of Tabernaemontana corymbosa. Their structures were elucidated on the basis of spectroscopic data, and the NMR data of 17-acetyl-tabernaecorymbosine A (4)
