Synthesis of azaheterocycles from oxime derivatives*
Electrophilic amination of Grignard reagents has been accomplished by using O-sulfonyloximes as amination reagents. Benzophenone O-sulfonyloxime derivatives react with Grignard reagents on sp2 nitrogen, yielding primary amines by successive hydrolysis of the resulting N-alkylimines. Various cyclic imines are synthesized by Pd-catalyzed reaction from olefinic oxime derivatives. That is, treatmen...
متن کاملSynthesis and Pesticide Activity of some New Arylic and Pyridylic Oxime Ether Derivatives of Ionone
Some oxime ether derivatives of α-ionone (4-(2,6,6-trimethyl-2-cyclohexen-1-yl)-3-buten-2-one) have been synthesized. Reaction of 4-(2,6,6-trimethyl-2-cyclohexen-1-yl)-3-buten-2-ketoxime with various chloro and fluoro aromatic and hetero aromatic compounds gave the corresponding oxime ether derivatives via aromatic nucleophilic substitution (SNAr). The structures of these co...
متن کاملSynthesis and In Vitro Antimicrobial Activity of 2,4- Difluorophenyl (piperidin-4-yl)methanone Oxime Derivatives
A series of new 2,4-difluorophenyl(piperidin-4-yl)methanone oxime derivatives 4a-h and 5a-e were synthesized by the reaction of 2,4-difluorophenyl(piperidin-4-yl)methanone oxime with various sulfonyl and acid chlorides. The synthesized compounds were characterized by elemental analyses, FTIR, 1 H NMR and LCMS spectral studies. All compounds were evaluated for in vitro antibacterial and antifung...
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...
postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
