Green MW/US‐Assisted Construction of Pyrano[2,3‐b]pyridines and Pyrazolo[3,4‐d]pyrimidinones: Pathway Control and Antibacterial Evaluation

open access: yesChemistry &Biodiversity, Volume 23, Issue 10, October 2026.
A rapid, green MW/US‐assisted route was developed for synthesizing coumarin/azacoumarin‐based fused heterocycles. It enables efficient construction of pyrano[2,3‐b]pyridines and pyrazolo[3,4‐d]pyrimidinones under mild conditions. FT‐IR, NMR, MS, and elemental analysis fully confirmed the structures of the new products.
