The reaction of 2‐alkynylanisoles/sulfides with SOCl₂ and DMSO was conducted to conveniently furnish the biologically interesting 3‐(methylthio)‐benzo[b]furans/thiophenes via intramolecular cyclization. DMSO acts as a solvent as well as a sulfur source and can also be replaced with DMSO‐d₆, enabling the incorporation of the SCD₃ moiety of DMSO‐d₆ to the 3‐position of the heterocyclic frameworks.
