Kumar, VipinSingh, DharmenderGujjarappa, RaghuramMalakar, Chandi C.Singh, Virender2024-01-212024-08-132024-01-212024-08-132021-03-16385541410.3987/COM-20-14383http://10.2.3.109/handle/32116/3209A proficient and feasible approach towards polysubstituted quinolone conjugated 4H-pyrans has been elucidated. The illustrated phenomenon concern with the base-mediated multicomponent reaction and subsequent copper-catalyzed hydroxylation of C-X bond emerging in an amide functionality. The developed reaction conditions showcased considerable substrate scope and functional group tolerance by giving the desired products in good yields. � 2021 Japan Institute of Heterocyclic Chemistry.
