Platinum-Catalyzed Tandem Indole Annulation/Arylation for the Synthesis of Diindolylmethanes and Indolo[3,2-b]carbazoles
摘要:
Various diindolylmethanes were prepared from propargylic ethers and substituted indoles via a platinum-catalyzed tandem indole annulation/arylation cascade. The resulting diindolylmethanes could be converted to natural product malassezin by formylation or indolo[3,2-b]carbazoles by cyclization.

Described is a method to make diindolylmethanes and indolyl/pyrrolylmethanes, The method includes the steps of contacting an ether comprising an arylpropargyl moiety and an amine-protected, substituted or unsubstituted aniline moiety with a substituted or unsubstituted indol or a substituted or unsubstituted pyrrole, in the presence of a metal-containing catalyst, for a time and at a temperature to cause an annulation/arylation cascade reaction that yields a diindolylmethane or a indolyl/pyrrolylmethane. The resulting compounds are effective to modulate activity of arylhydrocarbon receptors, to inhibit activity of PCSK9, and to stimulate secretion of glucagon-like peptide 1 in mammals.
