Multicomponent Cascade Assembly for Quinolinopyranpyrazole Architectures

Abstract

Abstract A highly efficient, multicomponent protocol for the construction of functionalized quinolinopyranpyrazole scaffolds with high stereoselectivity has been developed through the application of a domino reaction. All the quinolinopyranpyrazoles were synthesized under solvent‐ and catalyst‐free conditions and required no work‐up or column chromatography.
