2-(2-furyl)phenanthro[9,10-d]oxazole was synthesized by the reaction of 9,10-phenanthrenequinoneimine and furan-2-carbaldehyde in ethanol. Reactions of electrophilic substitution of this compound were investigated (nitration, bromination, sulfurization, formylation, acylation). Depending on the reaction conditions the electrophile attacks either the furan ring or the phenanthrene fragment. © 2015 Pleiades Publishing, Ltd. Source

2-(2-Furyl)-1H-naphto[2,3-d]imidazole was synthesised by interaction of 2,3-diaminonaphtalene with furfural in the conditions of Weidenhagen reaction. At its N-methylation in the KOH-DMSO system the 1-methyl-2-(2-furyl)-1H-naphto[2,3-d]imidazole was obtained, which we subjected to reactions of electrophilic substitution (nitration, bromination, sulfonation, formylation, and acylation). This compound possesses a specific reactivity: all reactions, as a rule, proceed at the naphthalene scaffold while the furan ring is not involved. © Pleiades Publishing, Ltd., 2014. Source

Abstract Influence of tetraethyl- and tetrabutylammonium salts on alcohols oxidation with the 4-acetylamino-2,2,6,6-tetramethylpiperidine-1-oxyl-iodine catalytic system has been studied. Addition of these salts inhibits the reaction and reduces the conversion. © Pleiades Publishing, Ltd., 2015. Source

2,3-Diaminopyridine and furfural in the conditions of Weidenhagen reaction give rise to 2-(furan-2-yl)-1(3)H-imidazo[4,5-b]pyridine, whose methylation in KOH-acetonee system affords isomeric 1-methyl-2-(furan-2-yl)-1H- and 3-methyl-2-(furan-2-yl)-3H-imidazo[4,5-b]pyridines. At the electrophilic substitution of the 1-methyl isomer (nitration, bromination, sulfation, formylation, acylation) depending on the conditions either furan ring, or pyridine fragment suffer the electrophilic attack. At its quaternization with methyl iodide in benzene N-methylpyridinium salt is obtained. © 2014 Pleiades Publishing, Ltd. Source
