4-Hydroxy-3-[(2E)-3-(3,4,5-trimethoxyphenyl)prop-2-enoyl]-2H-chromen-2-one

A new chalcone of the coumarin, C(21)H(18)O(7), containing an annulated α-pyrone ring, was obtained by condensation of the borate complex of acyl(hydroxy)coumarin with trimethoxybenzaldehyde. The structure exhibits intramolecular hydrogen bonding between the hydroxyl oxygen and the ketonic oxyge...
