Regioselective synthesis of heterocycles from 3-cyclohex-2-enyl-4- hydroxy-1-methylquinolin -2-(1h)-one

Article abstract of DOI:10.1080/00397919808004868

3-Cyclohex-2-enyl-4-hydroxy-1-methylquinolin-2(1H)-one (5) reacts with pyridine hydrotribromide in CH₂Cl₂ at 0-5°C for 0.75h to give a furo fused heterocycle 6 in 96% yield. Product 6 on treatment with KOH-EtOH eliminates HBr to give
