Effect of Substitution in Stannic Chloride–Mediated Heterocyclization of 4‐Allyl‐3‐hydroxyquinolin‐2(1H)‐ones
摘要:
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.
