    Reactions of nucleophilic, electrophilic substitution and cyclization in the synthesis of polyheterocyclic derivatives of 1,4-quinones
    (Видавництво Львівської політехніки, 2013) Shakh, Yurii; Kudrinetska, Anastasiia; Bolibrukh, Khrystyna; Karkhut, Andrii; Lytvyn, Bohdan; Polovkovych, Sviatoslav
    Reactions of nucleophilic substitution between 5-R-2,3-dichloro 1,4-naphthoquinones and 4-amino-5-heteryl- 4H-1,2,4-triazole-3-thioles were carried out. Modification of synthesized compounds by reactions of electrophilic substitution under the influence of acetyl chloride folllowed by the formation of mono- and diacetylated products. By the reaction of intramolecular cyclization tetracyclic systems containing thiadiazine fragment were synthesized.
