A Facile, ecofriendly, one-pot protocol for the synthesis of substituted 3-phenyl-furo[3,2-c]coumarins from in-situ generated α-halo ketones and 4-hydroxy coumarins in PEG-400 and water as a greener solvent. The developed protocol provides the better alternative to the existing method as it involves utilization of in-situ generated α-halo ketones and avoids the use of lachrymatric α-haloketones as well as toxic organic solvents.
