The salient features of this practical method are operational simplicity, avoidance of any organic solvents and tedious column chromatographic purification, clean reaction profiles, excellent yields, and gram-scale synthetic applicability. Keywords Keywords3-[3-(2-hydroxyphenyl)-3-oxo-1-arylpropyl]-4-hydroxycoumarins - warfarin analogues - water medium - cost-effective - green synthesis Full Text References References 1a Chen X, Liu Y, Furukawa N, Jin D.-Y, Savage GP, Stafford DW, Suhara Y, Williams CM, Tie J.-K.
