Regioselective synthesis of 1,4-disubstituted imidazoles.
A short and efficient synthesis of 1,4-disubstituted imidazoles has been developed which provides the desired products with complete regioselectivity. This protocol allows preparation of compounds which are challenging to prepare by current literature methods in a regioselective fashion, a sterically and electronically diverse range of N-substituents being accessible. The sequence involves an u...
متن کاملSynthesis and Bleaching Activity of 1-Ethyl- and 1 -Propy 1-5-Substituted Imidazoles
Twenty-eight 1-ethyland l-p ropyl-5-substitu ted imidazoles were synthesized and their bleaching activity was evaluated by using the lettuce seedling test. 5-Phenyl1-propylimidazole (1) caused distinct chlorosis, while none o f the com pounds with various alkenyl groups at the 5-position o f the im idazole ring showed this bleaching activity. In troduction o f a brom o, chloro, fluoro, methyl o...
متن کاملSynthesis, Characterization and Anticonvulsant Activity of Some Novel 4, 5-Disubstituted-1, 2, 4-Triazole Derivatives
Article history: Received on: 07/02/2017 Accepted on: 21/03/2017 Available online: 30/07/2017 The current therapy of epilepsy is associated with a number of side effects including sedation and hypnosis. Newer improved molecules are needed with lesser side effects and with improved physical properties. In view of these facts, a series of novel 4, 5-disubstituted-1,2,4-triazoles (6a-o) were synth...
متن کاملextraction and characterization of allium irancum plant extract and its application in the green synthesis of silver nano particles and oxidation of thiocarbony1 compounds
سنتز سبز نانوذرات فلزی (nps) درسالهای اخیر توجه بسیارزیادی را به خود جلب کرده است. زیرا این پروتوکل کم هزینه وسازگار با محیط زیست از روش های استاندارد سنتز. در این پایان نامه ما گزارش میکنیم یک روش ساده و سازگار با محیط زیست برای سنتز نانوذرات نقره با استفاده از محلول آبی عصاره گیاه allium iranicum به عنوان یک عامل کاهش دهنده ی طبیعی. نانو ذرات نقره مشخص شد با استفاده از تکنیک های uv-visible، x...
Synthesis and Leishmanicidal Activity of 1-[5-(5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl]-4-benzoylepiperazines
A series of (5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl derivatives 6a–6e have been synthesized and screened for in vitro anti-leishmanial activity against the promastigote form of L. major. The structure of Schiff bases were confirmed by 1H NMR, IR. Screening results indicate that all of the designed and synthesized final compounds (6a-6e) significantly reduced the viability of promastigotes ...
