Syntheses, Absorption and Fluorescence Spectra of 7-Hydroxy-3-pyridylcoumarins, their Esters, Ethers, and Quaternized Derivatives

7-Hydroxycoumarins 4 with a 2-, 3- or 4-pyridyl substituent in position 3, their ethers (3), esters (5, 6), and quaternized derivatives (7-9) have been synthesized by a generally applicable method starting from 2-hydroxy-4-methoxybenzaldehyde (1).The absorption and fluorescence spectra in methanol and water of different pH values are reported, and the effects of substituents on spectra and pKa values are discussed.
