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.
A direct method for the synthesis of 1,3,4-triarylpyrroles was achieved easily from cyclization of α-amino carbonylcompounds and aldehydes catalyzed by I2. Various substituted groups can be employed, and this reaction can proceed smoothly in moderate to good yields.
A simple and highly efficient one‐pot, three‐component synthesis of novelsubstitutedimidazolederivatives has been reported by the reaction of 3‐(2‐bromoacetyl)‐2H‐chromen‐2‐one, ammonium thiocyanate, and phenacyl aniline in the presence of acetic acid as a solvent under reflux condition with good yields. The structures of newly synthesized compounds were characterized by their analytical and spectral
