Khilya // Chemistry of Heterocyclic Compounds. – 2009. - № 10 – P. 1261.https://dspace.nuft.edu.ua/handle/123456789/3992The alkylation of o-cyanophenol by 4-chloromethylcoumarins and subsequent intramolecular condensation by the cyano and methylene groups gives substituted 4-(3-amino-2-benzofuranyl) coumarins. We studied the reactions of these compounds with acylating agents as well as with aldehydes, which lead to the 6H-[1]benzofuro[3,2-b]chromeno[4,3-d]pyridin-6-one system as the result of consecutive transformations.other4-хлорметилкумаринкафедра харчової хімії4-(3-amino-2-benzofuranyl)coumarinо-ціанофенол4-(3-амінобензофуран-2-іл)кумарин1,2-дигідропіридини5H-хромено[3,4-c]піридин-5-они6H-[1]бензофуро[3,2-b]хромено[4,3-d]піридин-6-онио-цианофенол4-(3-аминобензофуран-2-ил)кумарин1,2-дигидропиридины5H-хромено[3,4-c]пиридин-5-оны6H-[1]бензофуро[3,2-b]хромено[4,3-d]пиридин-6-оны6H-[1]benzofuro[3,2-b]-chromeno[4,3-d]pyridin-6-one1,2-dihydropyridine4-chloromethylcoumarin5H-chromeno[3,4-c] pyridin-5-one, o-cyanophenol.Article
