Reported herein is a transition-metal-free protocol for a regio- and diastereoselective synthesis of hydroxyalkyl group-embedded N-arylbenzo[b][1,4]oxazines and N-arylindolines based on an epoxide-opening cyclization/double Smiles rearrangement cascade of p-nosylamide-tethered epoxides. To the best of our knowledge, this is the first report of the integration of epoxide-opening cyclization with Smiles
