Abstract
Effect of substituents at the allylic position in a stannic chloride–iodine–mediated heterocyclization of 4‐allyl‐3‐hydroxyquinolin‐2(1H)‐ones for the regioselective formation of five‐ and six‐membered heterocyclic rings has been rationalized by the application of restricted Hatree–Fock calculation.
