Beryozkina T. Formation of the six-membered azaheterocycles in reactions of beta-aroylacrylic acids with binucleophiles.

Objects - beta-aroylacrylic and 3-aroyl-2,3-dibromopropionic acids, quinoxaline-2-ones, pteridines; methods: synthesis, UV-, IR-, NMR-spectroscopy, mass-spectrometry, X-ray analysis, quantum chemical calculations; results - the transformation of 3-(2-aryl-2-oxoethyl)quinoxaline-2-ones and their heteroanalogs into 3-aryl-2-methylinedenarboxyquinoxalines and dihydropteridine derivatives were proved, the intermediates of the hetarylation of enone systems with 4-aryl-1,2-diaminoimidazoles were obtained, 3-(2-aryl-2-oxoethyl)benzo-1,4-thiazine-3-ones are the products of interaction of beta-aroylacrylic acids with o-aminothiophenole; volume of providing - making of the preparative methods of synthesis of fuzed nitrogen containing heterocycles.
