A simple and environmentally friendly strategy for the synthesis of E-ortho-hydroxystilbenes has been established. Two kinds of α,β-unsaturated aromatic lactones, i.e. the 3-arylcoumarins and the isoaurones, could both readily undergo a cascade hydrolyzation/decarboxylation reaction in the presence of KOH in ethylene glycol to afford the desired E-ortho-hydroxystilbenes in moderate to high yields.
Synthesis of 3-arylcoumarins by FeCL3-promoted cyclization of orto-methoxy-substituted (E)-2,3-diphenylpropenoic acids or their methyl esters

3-Arylcoumarins were conveniently synthesized in excellent yields by an iron(III) chloride-promoted tandem reaction using methoxy-substituted (E)-2,3-diphenylpropenoic acids or their methyl esters. The structure of 3-(4-methoxyphenyl)coumarin was establis

The oxidation of eight (E)-α-phenylcinnamic acids with manganese(III) acetate in boiling acetic acid containing acetic anhydride gave 3-phenylcoumarins, 3-phenyl-1-oxaspirodeca-3,7,9-triene-2,6-diones, 2-phenylbenzofurans, 3-(acetoxymethyl)-2-phenylbenzofurans, 3-formyl-2-phenylbenzofuran, 2-acetoxy-2-phenyl-3(2H)-benzofuranones, (Z)-Α-acetoxystilbenes, 2-acetoxy-1,2-diphenylethanones, 5-acetoxy-4,5-diphenyl-2(5H)-furanones, and diphenylacetylene.Tha reaction pathways are discussed.
