Abstract

Synthesis of a series of 2-(2,5-dihydro-2,5-dioxopyrano[3,2-c]chromen-4-yl)acetic acid. (4a-g) was achieved from different substituted 4-hydroxycoumarin, anhydrous citric acid and using H₂SO₄ added and 10°C with string. The structures of the products were supported by FTIR, PMR and mass spectral data.
