SYNTHESIS AND PHOTOPHYSICAL PROPERTIES OF THE PRODUCTS OF THE REACTION OF 5-METHYL-7-PHENYL[1,3]OXAZOLO[5,4-b]PYRIDIN-2(1H)-ONE WITH AMINO ACIDS

Abstract
The reaction of amino acid esters with 7-phenyl[1,3]oxazolo[5,4-b]pyridin-2(1H)-one led to the derivatives of 3-(2-oxo-4-phenyl-1,2-dihydropyridin-3-yl)imidazolidine-2,4-diones and ethyl 2-[3-(2-oxo-4-phenyl-1,2-dihydropyridin-3-yl)ureido]acetates, as well as several of their structural analogs. The photophysical properties of the synthesized compounds were investigated.
