A facile solvent- and catalyst-free method for the synthesis of a series of new hydroxylated 2,4,6-trisubstituted pyridinesundermicrowave irradiation was developed. The expected products were obtained through a simplified purification process without protection of the hydroxyl group. UV-Vis and fluorescence spectra of these conjugated multi-hydroxyl compounds were also investigated.
