Environmentally Benign Synthesis of Tetrahydroindeno[1,2-b]Pyrrole-3-carboxylate Derivatives as Potential Antiinflammatory Agents
A new series of tetrahydroindeno[1,2-b]pyrrole-3-carboxylate derivatives(4) were synthesized by reaction of 5-amino-2-mercapto benzimidazole with 1,3-dicarbonyls and activated carbonyl compounds using ceric ammonium nitrate catalyst by a three component one-pot reaction. Structures of these compounds were established on the basis of infrared spectroscopy, proton nuclear magnetic resonance, carb...
متن کاملEfficient Electrochemical Synthesis, Antimicrobial and Antiinflammatory Activity of 2–amino-5-substituted- 1,3,4-oxadiazole Derivatives
An efficient electrochemical method for the preparation of 2-amino-5-substituted-1,3,4-oxadiazoles (4a-k) at platinum anode through the electrooxidation of semicarbazone (3a-k) at controlled potential electrolysis has been reported in the present study. The electrolysis was carried out in the acetic acid solvent and lithium perchlorate was used as supporting electrolyte. The products were chara...
متن کاملImproved preparation of sulfur substituted 3-vinylpyrrole and its application to the syntheses of chuangxinmycin derivatives.
Sulfur substituted 3-vinylpyrrole 10 was prepared from 3-thio-acetylpyrrole 9 by alkylation with alkyl halide in the presence of propylene oxide. Functionalized 4-alkylthioindoles were made by Diels-Alder reaction of the 3-vinylpyrrole 10 with dienophiles. Chuangxinmycin analogues were synthesized by using some of the functionalized 4-alkylthioindoles as key intermediates.
متن کاملSyntheses of Substituted 1,3,4-Oxadiazole, 1,3,4-Thiadiazole and 1,2,4-Triazole Derivatives as Potential Antimicrobial Agents
A series of 2-(4-nitro-1-imidazolylmethyl)-1,3,4-oxadiazole, 1,3,4-triazole and 3-(4-nitro-1-imidazolylmethyl)-1,2,4-triazole derivatives were synthesized and tested for their antimicrobial activity. Some of the tested compounds were active against Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilis, Clostridium difficile, Aspergillus niger and Cryptococcus neoformans.
متن کاملSynthesis of 1, 3-diaryl Substituted Iodobenzene Derivatives
The synthesis and characterization a new derivatives of 2'-iodo-meta terphenyl from the reaction ofexcess aryl-Grignard and 2, 6- dichloroiodobenzene with quenching of m-terphenyl-2'-magnesiumbromide by iodine is reported. Via the reactions three carbon-carbon bonds are constructed and mterphenylsare obtained in good yields.
