By using N,N‐dimethylformamide (DMF) as a methylenating reagent, the copper‐catalyzed CH activation of indole was demonstrated as an efficient and facile protocol for synthesizing 3,3′‐diindolylmethane (DIM) and its derivatives. The results indicate that copper chloride was the best catalyst among the investigated transition metal salts, which affords an excellent regioselectivity and good yield when

A new method for the synthesis of bi‐heteroaryls is reported, based on the umpolung of indoles with benziodoxol(on)e hypervalentiodinereagents (IndoleBX). The oxidative coupling of IndoleBX with an equimolar amount of electron‐rich benzenes, indoles, pyrroles, and thiophenes proceeded under mild transition‐metal‐free conditions. Functionalized non‐symmetrical bi‐indolyl heterocycles were accessed
Disclosed are substituted pyrroles having the formula
These compounds and their pharmaceutically acceptable salts are useful in the treatment and/or control of cell proliferative disorders, in particular cancer. Also disclosed are pharmaceutical compositions containing the foregoing compounds.
