An interrupted Pummerer coupling/[3,3]-sigmatropic rearrangement cascade allows the direct and metal free dual vicinal functionalisation of heterocycles. For example, C3 thio, C2 allyl indoles are prepared in one synthetic operation from the union of the parent indoles and allyl sulfoxides. A dual vicinal functionalisation cascade involving the union of heterocycles and allyl sulfoxides is described. In particular, the approach provides efficient one-step access to biologically relevant and synthetically important C3 thio, C2 carbo substituted indoles. The reaction operates under mild, metal free conditions and without directing groups, via an interrupted Pummerer coupling of activated allyl sulfoxides, generating allyl heteroaryl sulfonium salts that are predisposed to a charge accelerated [3,3]-sigmatropic rearrangement.
