Synthesis of Nitroalkenes Involving a Cooperative Catalytic Action of Iron(III) and Piperidine: A One‐Pot Synthetic Strategy to 3‐Alkylindoles, 2H‐Chromenes and N‐Arylpyrrole

Abstract

AbstractAn efficient and simple strategy has been developed to synthesize various substituted nitroalkenes involving a cooperative catalytic system of FeCl3 and piperidine. This dual catalytic protocol simultaneously activates both electrophile and nucleophile and works under mild reaction conditions so that many sensitive functional groups were tolerated. Moreover, this cooperative catalytic reaction is also suitable for various one‐pot reactions involving nitroalkenes such as, 2H‐chromenes, N‐arylpyrrole and Michael reaction with indole. Notably, this method is low‐cost, efficient and environmentally friendly.
