Rhodium(iii)-catalyzed C–C coupling of 7-azaindoles with vinyl acetates and allyl acetates

Abstract

The behaviour of electron-rich alkenes with 7-azaindoles in rhodium(III)-catalyzed C–H activation is investigated. Various substituted vinyl acetates and allyl acetates as coupling partners reacted smoothly providing a wide variety of 7-azaindole derivatives, and the selectivity of the coupling reaction is alkene-dependent. In addition, the approaches of rhodium(III)-catalyzed dehydrogenative Heck-type reaction (DHR) and carbonylation reaction were quite novel and simple.
