single-step synthesis of multi-component spirobarbiturates using ionic liquids and synthesis of substituted pyridine filled with catalysts supported on solid substrate
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
15 صفحه اولBiopolymer Synthesis on Solid Supports
The concept of solid phase synthesis began as a new approach to the preparation of peptides, but has been extended to the synthesis of polynucleotides, polysaccharides, polyamides and a variety of other classes of compounds. The solid support simplifies and accelerates the synthetic process, aids the separation of reagents and by-products, and reduces problems of insolubility of intermediates. ...
متن کاملSYNTHESIS AND ANTIMICROBIAL ACTIVITY OF 3-(2’-n-BUTYLBENZOFURAN-3’-YL)-5-ARYL-4, 5-DIHYDRO-1H-PYRAZOLES.
3-(2’-n-butylbenzofuran-3’-yl)-5-aryl-4, 5-dihydro-1H-pyrazoles (4a-4k) have been synthesized. The synthesized products have been assayed for their antimicrobial activity against Gram+ve, Gram-ve bacteria and fungi. All the synthesized products were assigned with IR, 1HNMR, Mass Spectra, TLC, and elemental analysis. Some of the products showed moderate activi...

متن کاملAn Expeditious Synthesis of New 5-acetyl-4-(4’-alkyloxyphenyl)- 3-cyano-6-methylpyridine-2(1H)-thiones and Derivatives
A convergent synthesis of 5-acetyl-4-(4'-alkyloxyphenyl)-3-cyano-6-methylpyridine-2(1H)-thiones and their derivatives S-alkylthiopyridines was described. The main steps towards the formation of the title compounds involve the reactions of 4-alkyloxybenzaldehydes with 2-cyanothioacetamide to afford 2-cyano-3(4'-alkyloxyphenyl)prop-2-enethioamides which then reacted with acetylacetone prior to th...
