Synthesis of some novel class of isoxazoline and isoxazolidine derivatives in ionic liquid via 1,3-dipolar cycloaddition reaction of dihydropyran derived nitrones and their antimicrobial activities
1,3-Dipolar cycloaddition of dihydropyran derived nitrones synthesized from 2,3 dihydro 4H-pyran and various hydroxylamines, with electron deficient alkynes are found to have significant rate acceleration and improved yields of isoxazolines in 1-Butyl-3-methylimidazolium based ionic liquids while with enals exclusively endo isoxazolidines are obtained with high selectivity. Synthetic potentiali...
متن کاملSynthesis of novel spiro-isoxazoline and spiro-isoxazolidine derivatives of tomentosin
Plants have a long history as therapeutics in the treatment of human diseases and have been a continuous source of inspiration for the development of new medicines. Among them, the genus Inula (Asteraceae) comprisesmore than 100 species, many of which are widely used in traditional medicine for a variety of biological purposes including anti-inammatory, anti-cancer and antibacterial activities...
متن کاملSynthesis and Antioxidant Activities of [5-fluoro N, N'-bis (salicylidene) ethylenediamine] and [3, 5-fluoro N, N'-bis (salicylidene) ethylenediamine] Manganese (III) Complexes
Antioxidants act as free radical scavengers in the oxidation processes. Thus, they will certainly play diverse roles in the biological systems and the therapy of a wide variety of diseases. Regarding this fact, in the present study, we synthesized two new salen ligand compounds by the condensation of ethylendiamine and salicylaldehyde derivatives in excellent yields.The structures of ...

متن کاملpart a: application of n-(p-toluenesulfonyl) imidazole (tsim) and triphenylphosphine/carbon tetrachloride in several organic transformations part b: application of 8-bromocaffeine for synthesis of some novel 8-caffeinyl derivatives
بخش اول این پایان نامه به طور عمده بر توسعه کاربردهای جدید n-(پارا-تولوئن سولفونیل) ایمیدازول (tsim) و تری فنیل فسفین/ تتراکلرید کربن در تبدیل گروههای عاملی به یکدیگر استوار است. نظر به تنوع زیاد، دردسترس بودن، سمیت کمتر و نقل و انتقال آسان تر الکل ها نسبت به آلکیل هالیدها، تبدیل مستقیم گروه هیدروکسیل به گروه های عاملی دیگر مثل آزید، نیتریل و استر یکی از مهم ترین تبدیلات در سنتزهای آلی است. با ...
