Abstract

Проаналізовані та систематизовані літературні джерела, які стосуються біологічної активності піридо [3,2-d] reaction conditions and the direction of intramolecular cyclization. It has been found that cyclization of 2-allyl(cinnamyl)aminopyrido[3,2-d]pyrimidines in the presence of polyphosphoric acid leads to linear forms of imidazopyridopyrimidinon, while in the conditions of iodocyclization and arylsulfenylation the tricyclic imidazoannelated pyridopyrimidines of the angular structure are mainly formed. Regioselectivity of annelation of the 2-cinnamyl moiety of aminopyrido[3,2-d]pyrimidine has been found. In particular, treatment of 2-cinnamylaminopyrido[3,2-d]pyrimidine with arylsulphenylchlorides or polyphosphoric acid results in formation of the linear tetrahydropyrido[3,2-d]pyrimidines, and iodocyclization leads to an angular isomer. The virtual screening of the compounds synthesized has shown that they may potentially exhibit a wide range of bioactivity. ИМИДАЗО-И ПИРИМИДИНОАННЕЛИРОВАННЫЕ ПИРИДО[3,2-d]ПИРИМИДИНЫ.
