D–A–D–T-type four-component radical dual-difunctionalization and acylative azidation of two different alkenes

Abstract

From a single alkene to two different alkenes! An iron-catalyzed four-component reaction involving an aldehyde, two different alkenes and TMSN₃ is developed to assemble these four reactants in an orderly fashion based on the inherent nucleophilic/electrophilic reaction activity of the radicals and alkenes via a double radical addition, providing various multifunctional compounds containing an azido group and two carbonyl groups.
