Resumo: Various α-acyloxy carboxyamides were easily obtained combining three building blocks in one step: a carboxylic acid, an aldehyde and an isonitrile (Passerini reaction), using microwave irradiation under solvent-free conditions. The products were obtained in good yields (61-90%) and in short reaction times (< 5 min), using two different temperatures (60 and 120 ºC). At 120 ºC, the yields were higher and the reactions faster (< 1 min). Most of the obtained products are multifunctional allowing their application in consecutive Passerini reactions

Os produtos foram obtidos em bons rendimentos (61-90%) e em tempos reacionais bastante curtos (< 5 min), usando duas diferentes temperaturas (60 e 120 ºC). A 120 ºC, os rendimentos foram mais altos e as reações mais rápidas (< 1 min). Vários dos produtos formados são multifuncionais, possibilitando sua aplicação em reações de Passerini consecutivasEm processamentoSociedade Brasileira de Química2017-12-07T04:56:33Z2017-12-07T04:56:33Z2011info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfJ.
