A series of 3-R-6,8,8,9-tetramethyl-2H-pyrano[3,2-g]quinolin-2-ones was obtained by condensation of 7-hydroxy-1,2,2,4-tetramethylhydroquinoline-6-carbaldehydes with aroylacetic acid esters. The dependence of the UV and photoluminescence spectra on the structure of the obtained compounds was studied.
