Kharchenko, O. S. Detistov, V. D. Orlov // J. Comb. Chem. – 2009. – Vol. 11. – P. 216–219.1520-4766https://repo.knmu.edu.ua/handle/123456789/808We have developed a liquid-phase route for combinatorial synthesis of novel substituted 5-(1,2,4-oxadiazol-5-yl)-3,4 dihydropyrimidine-2(1H)-thiones. Biginelli-type three-component condensation of 1-(3 aryl-1,2,4-oxadiazol-5-yl)acetones, thiourea, and benzaldehydes is shown to result in new 5-(1,2,4-oxadiazol-5-yl)-3,4-dihydropyrimidine-2(1H)-thione heterocyclic system. If salicylaldehydes are used in this reaction, a mixture of 5-(1,2,4-oxadiazol-5-yl)-3,4-dihydropyrimidine-2(1H)-thiones and 11-(1,2,4-oxadiazol-5-yl)-2,3,5,6-tetrahydro-4H-2,6-methano-1,3,5-benzoxadiazocine-4-thiones is formed.en1,2,4-oxadiazole3,4-dihydropyrimidinecombinatorial synthesisliquid-phase routeArticle
