Аннотация: Fluorinated 3-oxo esters react with aldehydes and 3-amino-1,2,4-triazoles and 5-aminotetrazoles to give, respectively, 7-alkyl(aryl)-6-alkoxycarbonyl-5-fluoroalkyl-1,2,4-triazolo[1,5-a]pyrimidines and -tetra-zolo[1,5-a]pyrimidines. The same heterocyclic products can be obtained by reaction of 2-benzylidene-2-fluoroacyl esters with the corresponding aminoazoles

    Nucleophilic ring-opening of the azole and azine moieties in 6-nitro-1,2,4-triazolo[1,5-a]pyrimidin-7-ones [Electronic resource] / E. N. Ulomskii, V. V. Voronin, V. L. Rusinov, O. N.

Аннотация: The effects of the nature of the nucleophile and the structure of 6-nitrotriazolo[1,5-a]pyrimidinones on the direction of the ring opening were investigated. The triazole ring is opened under the action of strong bases, such as alkoxides or alkalis, to form 2-cyanoaminopyrimidinones and then 2-aminopyrimidinones. The results of the reactions with N-nucleophiles depend on the accessibility of position 5 of the heterocycle. Thus, sterically hindered secondary amines react with 5-methyltriazolopyrimidinones to give 2-guanidinopyrimidinones and then 2-aminopyrimidinones. In the absence of a substituent at position 5, the azine ring is opened to form 4-alkyl-3-amino-1,2,4-triazoles and 3-amino-2-nitroacrylamides. Under the action of primary amines, only the pyrimidine fragment is cleaved

ALFA-HYDROXIMINO KETONES -- 1,2,3-TRIAZOLES -- ALLOBETULONE
Аннотация: Lupane and 18αH-oleanane α-hydroximino ketones were used to synthesize derivatives condensed at ring A with a substituted azole fragment, namely, C(2)-C(3)-fused oxazoles and 1,2,3-triazoles. Triterpene isoxazoles fused at the C(1)-C(2) bond are described for the first time. An optimized method was proposed for the synthesis of unsubstituted 1,2,3-triazoles, displaying cytotoxic activity (IC50 8.4-40.7 μM) relative to rhabdomyosarcoma, lung carcinoma, and MS melanoma cell lines.

AZIDES -- CYCLOADDITION -- NITROGEN HETEROCYCLES
Аннотация: The reactions of β-azolylenamines 1 with sulfonyl azides 2 in acetonitrile furnished 1H-4-(azol-5-yl)-1,2,3-triazoles 3 in yields of 52-93%. β-Benzoylenaminones and β-nitroenamine of type 1 also reacted with tosyl azide to form the same type of products 3, proving the generality and efficiency of the method for the synthesis of N-unsubstituted 1,2,3-triazoles. On the other hand, the reactions of 3-(1-aryl-1,2,3-triazol-5-yl)enamines with tosyl azide in the absence of a solvent afforded a mixture of (E)-1-dimethylamino-2-tosylaminoethenes 5 and N,N-dimethyl-N′- tosylformamidine 6 in yields of 40-50 and 20%, respectively. The formation of a variety of compounds from the reactions of enamines 1 with sulfonyl azides 2 is rationalized by the various possible transformations of the intermediate 5-dimethylamino-1,2,3-triazolines

SYNTHETIC METHODS -- nUCLEOPHILIC ADDITION -- OXIDATIVE DEQUATERNIZATION
Аннотация: A one-pot approach for the synthesis of 2-aryl-5-amino-1,2,3-triazoles is reported. This approach involves a tandem nucleophilic addition of alkylamines to hydrazonoyl cyanides and in situ oxidative cyclization of the resulting 2-(aryl-azo)ethene-1,1-diamines in the presence of copper(II) acetate and air. The described one-pot procedure is characterized by good yields, excellent selectivity, methodical simplicity, and uses readily available chemicals. This method was applied to the gram-scale synthesis of 2-aryl-1,2,3-triazoles.

1,2,3-TRIAZOLES -- ARYNE-MEDIATED TRANSFORMATIONS -- CAOSAMBHWGMFEW-UHFFFAOYSA-N -- CYFQLMLVDSTHGC-UHFFFAOYSA-N -- FLUOROARENES
Аннотация: A number of novel fluorinated derivatives of the family of pyrido[1,2-a]indole fluorophores have first been synthesized via the aryne-mediated domino transformations of 5-(perfluorophenyl)-3-(pyridin-2-yl)-1,2,4-triazines. A comprehensive study of photophysical properties of the obtained polyfluoroaryl substituted derivatives, in which polyfluoroaryl, 1,2,3-triazole, and pyridoindole subunits contribute to a joint chromophore system, has shown that these compounds proved to exhibit a fluoresce with green light in acetonitrile solutions.
