Alkaline earth metal catalyzed cascade, one-pot, solvent-free, and scalable synthesis of pyranocoumarins and benzo[b]pyrans

Ca(OTf)2 catalyzed, cascade, one-pot, conjugate addition and annulation of various nucleophiles to the α,β-unsaturated carbonyl compounds for the synthesis of biologically potent pyranocoumarins and benzo[b]pyrans has been illustrated. This one

Efficient route to highly functionalized chalcone-based pyranocoumarins via iodine-promoted michael addition followed by cyclization of 4-hydroxycoumarins

Molecular iodine is used as an efficient promoter in the regioselective synthesis of highly functionalized chalcone-based pyranocoumarin derivatives using 4-hydroxycoumarin in acetic acid solvent at 100 °C. Under optimized reaction conditions, our protoco
