RESUMO

Vários pirróis N-substituídos foram sintetizados pela reação de γ-dicetonas (R¹C(O)CH2CH2C(O)R²: R¹, R² = Me, Ph) com aminas (RNH2: R = Alkyl, Aryl, TsNH) ou diaminas (1,6-diaminohexano and 1,2-diaminoetano) na presença de tribrometo de índio, tricloreto de índio ou trifluorometanossulfonato de índio a temperatura ambiente e sem solventes. O protocolo envolve operações simples e os produtos são isolados em excelentes rendimentos (81-98%).
