Resumo: | In this present work, an unprecedented series of 4-((4-((arylchalcogen)methyl)-1H-1,2,3-triazol-1-yl) methyl)-2-phenylchalcogenazole 20 and 21 was synthesized with interest in the potential biological, because to the presence of different heterocyclic nucleus. The 4-(chloromethyl)-2-phenylchalcogenazoles 6 and 7 were obtained through a cyclization reaction of benzochalcogenoamides 3 and 4 with 1,3- dichloroacetone 5, with yields of 55% and 80%. For the synthesis reaction of 4-(azidomethyl)-2-phenyl- 1,3-chalcogenazoles 10 and 11, were used 4-(chloromethyl)-2-phenylchalcogenazoles 6 and 7, potassium iodide and sodium azide 9, of the yields were 55% and 60%. Through the Click reaction type, catalyzed by copper iodide, between 4-(azidomethyl)-2-phenyl-1,3-chalcogenazoles (10; 11) and propargyl alcohol 12, the formation of (1-((2-phenylchalcogenazo-4-yl)methyl)-1H-1,2,3-triazo-4-yl)methanol 13 and 14, with yields of 88% and 76%, respectively. Subsequently, the protection of the alcohol function of (1-((2- phenylchalcogenazol-4-yl)methyl)-1H-1,2,3-triazo-4-yl)methanol 13 and 14 was performed with mesyl chloride 15, where yields varied from 67% to 60% in obtaining (1-(((2-phenylchalcogenazol-4-yl)methyl)- 1H-1,2,3-triazol-4-yl) methanesulfonate 16 and 17, respectively. From the nucleophilic substitution reaction, optimized, between (1-(((2-phenylchalcogenazol-4-yl)methyl)-1H-1,2,3-triazol-4- yl)methanesulfonates (16, 17) and diphenyl dichalcogenides 18 and 19 take to the formation of the products desired, the 4-((4-((arylchalcogen)methyl)-1H-1,2,3-triazol-1-yl) methyl)-2-phenylchalcogenazole 20 and 21, with yields of 47% to 94%. |

Os 4-(clorometil)-2-fenilcalcogenazóis 6 e 7 foram obtidos por meio de uma reação de ciclização das benzocalcogenoamidas 3 e 4 com a 1,3-dicloroacetona 5, com rendimentos de 55% e 80%. Para reação de síntese dos 4-(azidometil)-2-fenil-1,3-calcogenazóis 10 e 11 foram utilizados os 4-(clorometil)-2-fenilcalcogenazóis 6 e 7, o iodeto de potássio e a azida de sódio 9, os rendimentos foram de 55% e 60%. Através da reação tipo Click, catalisada por iodeto de cobre, entre os 4-(azidometil)- 2-fenil-1,3-calcogenazóis (10; 11) e o álcool propargílico 12, levou-se a formação dos (1-((2- fenilcalcogenazol-4-il)metil)-1H-1,2,3-triazol-4-il)metanol 13 e 14, com rendimentos de 88% e 76%. Posteriormente, realizou-se a proteção da função álcool dos (1-((2-fenilcalcogenazo-4-il)metil)-1H-1,2,3- triazo-4-il)metanol 13 e 14 com o cloreto de mesila 15, onde os rendimentos variaram de 67% a 60% na obtenção dos metanossulfonato de (1-((2-fenilcalcogenazol-4-il)metil)-1H-1,2,3-triazol-4-il)metila 16 e 17, respectivamente. A partir da reação de substituição nucleofílica, devidamente otimizada, entre os metanossulfonatos de (1-((2-fenilcalcogenazol-4-il)metil)-1H-1,2,3-triazol-4-il)metila (16, 17) e os dicalcogenetos de difenila 18 e 19 levou-se a formação dos produtos desejados, os 4-((4- ((arilcalcogeno)metil)-1H-1,2,3-triazol-1-il)metil)-2-fenilcalcogenazóis 20 e 21, com rendimentos que variaram de 47% a 94%.Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPqCoordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESFundação de Amparo à Pesquisa do Estado do Rio Grande do Sul - FAPERGSporUniversidade Federal de Santa MariaCentro de Ciências Naturais e ExatasPrograma de Pós-Graduação em QuímicaUFSMBrasilQuímicaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessOrganocalcogêniosCalcogenazolTriazolOrganochalcogenChalcogenazoleTriazoleCNPQ::CIENCIAS EXATAS E DA TERRA::QUIMICASíntese de 1,2,3-triazóis-1,4-dissubstituídos contendo organocalcogênios derivados de 4-(azidometil)-2-fenil-1,3-calcogenazóis via reação de cicloadição 1,3-dipolarSynthesis of 1,2,3-triazoles-1,4-dissubstitutes containing organochalcogens derived from 4- (azidomethil) -2-phenyl-1,3- chalcogenazoles via 1,3-dipolar cycloaddition reactioninfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisDornelles, Lucianohttp://lattes.cnpq.br/7629319262073140Rodrigues, Oscar Endrigo DornelesIglesias, Bernardo AlmeidaAppelt, Helmoz Roseniaimhttp://lattes.cnpq.br/2425851333801401Bernardy, Silvia1006000000006006006006006b4b1c8a-fdd1-49f0-a8ce-2d891b6579b69854645d-c8cd-4599-9de6-f813b2aaf3e76721ab73-0457-4ffc-aa9d-bda83c8246ee483d6d0c-e419-454b-b413-1a51673258c34684f279-563c-45a1-a01d-7d0ddd2378cbreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALDIS_PPGQUIMICA_2020_BERNARDY_SILVIA.pdfDIS_PPGQUIMICA_2020_BERNARDY_SILVIA.pdfDissertaçãoapplication/pdf4548692http://repositorio.ufsm.br/bitstream/1/22999/1/DIS_PPGQUIMICA_2020_BERNARDY_SILVIA.pdf2b02971f8717007ec7b7b9808285e6d0MD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;
