Research on antibacterial and antifungal agents. VIII. synthesis and antimicrobial activity of 1,4-diarylpyrroles
摘要:
The synthesis and the antimicrobial activity of 1,4-diarylpyrroles are reported. The obtained data in comparison with pyrrolnitrin show that many acid derivatives 4 exhibit a selective activity against some strains of Candida spp and poor activity against strains of Candida albicans. All ester derivatives 3 are inactive. The results obtained are discussed on the basis of structure-activity relationships.

Abstract A facile, convenient, and multicomponent coupling strategy for the synthesis of highly functionalized pyrroles is developed using graphite as a catalyst, but devoid of moisture-sensitive metal catalysts and corrosive acidic reagents. This method involves four-component coupling reactions of ethyl acetoacetate compound or diethyl acetylene dicarboxylate, amines, aromatic aldehydes, and nitromethane
Triethanolammonium Acetate ([TEAH][OAc]) as a Recyclable Promoter and Medium for Green and Four-component Synthesis of Polyfunctionalized Pyrrole Derivatives
Multi-component synthesis of functionalized pyrrole derivatives was achieved via a fourcomponent condensation reaction of ethyl acetoacetate/ methyl acetoacetate, aromatic amines, nitromethane, and aromatic aldehydes usingtriethanolammoniumacetate ([TEAH][OAc]) ionicliquid as a green solvent and catalyst. Easy access to highly substituted pyrroles, reusability of the catalyst, broad substrate scopes
