The ring expansion of bicyclic heterocycles bearing an exocyclic double bond promoted by Koser's reagent [hydroxy(tosyloxy)iodobenzene, HTIB] is a mild, practical, and metal-free methodology to access seven-membered rings containing fused furan, indole, pyrrole, and thiophene heterocycles providing an entry to structurally challenging bioactive natural products as well as pharmaceuticals. Here we describe
