Pseudo Multicomponent Reaction: Synthesis of Fused Pyrano Biscoumarin Analogs from 1,2-diols

A simple and efficient method has been developed for the synthesis of fused pyrano biscoumarins using lead tetraacetate as an oxidizing agent by the condensation of one equivalent of 1,2-diols and four equivalent of 4-hydroxy coumarin in acetonitrile as solvent at 80°C with good to excellent yields.

Synthesis, structure, antimicrobial and antioxidant investigations of dicoumarol and related compounds

Different substituted 3,3′-arylidenebis-4-hydroxycoumarins (1-7) and tetrakis-4-hydroxycoumarin derivative 8 are the final products when 4-hydroxycoumarin and aromatic aldehydes containing different groups in ortho, meta or para positions condense in boil
