[BMIm]HSO4 as a Green and Highly Efficient Catalyst for One-pot Synthesis of 3-Substituted Indoles under Ultrasound Irradiation
A practical and green synthesis of 3-substituted indoles is reported via three-component coupling reaction of indoles, aldehydes and N-methylaniline in the presence of the acidic ionic liquid 1-butyl-3-methylimidazolium hydrogen sulfate ([BMIm]HSO4) under ultrasound irradiation at room temperature. The significant features of this procedure are high yields of the products, simple work-up, opera...

Synthesis of 2-phenyl-5-sulpha/substituted-3- substituted phenyl azo indoles used as antifertility agent
–A novel series of 2-phenyl-5-sulpha/substituted-3-phenyl substituted azo indoles have been synthesized and tested as an antifertility activity in mature albino mice. The tested compounds showed significant antifertility activity. Keywords––Synthesis, Antifertility activity, Indore, Azo indoles, chemical analysis.
متن کاملSynthesis of amino-substituted indoles using the Bartoli reaction.
We report herein the concise preparation of a range of functionalised aminoindoles via a new application of the Bartoli reaction. Scope and limitations of the methodology have been extensively studied to reveal the importance of protecting groups and substitution patterns. The use of amino substituted nitroanilines for the Bartoli reaction is to our knowledge unprecedented. Our work thus repres...
متن کاملNano TiO2@SiO2 as an efficient and reusable catalyst for the synthesis of multi-substituted imidazoles
Nano TiO2 supported on SiO2 (Nano TiO2@SiO2) as a solid Lewis acid, was described to be an effective and reusable catalyst for one-pot three-component reaction of benzil, aryl aldehydes and ammonium acetate for the synthesis 2-aryl-4,5-diphenyl-1H-imdazoles synthesis. To explore the high efficacy of the catalytic system the four-component cyclization of benzil, aryl aldehydes, ammonium acetate ...
