Heterocyclic Synthesis with Nitriles: A Novel Synthesis of Some Thiophene and Thieno[2,3-d]pyrimidine Derivatives, II [1]
2-Amino-3-functionally substituted thiophene de rivatives are important intermediates to the phar maceutically important thieno[2,3-d]pyrimidines [2]. These thiophene derivatives were available from the procedures published by K. Gewald [3, 4] via either the reaction of a-methylene ketones with active methylene nitriles in presence of elementary sulphur of from a-mercaptoketones and active me...
متن کاملsynthesis of new heterocyclic system n7-ethyl-5-methyl[1,2,4]triazolo[4,3:1,2]pyrimido[4,5d][1,3]thiazol-7-amine & synthesis of novel 7-methyl-3,5-di(alkhylsulfanyl) [1,2,4]triazolo[4,3-c]pyrimidine derivatives
در این تحقیق، ابتدا از واکنش 5-برمو-2-کلرو-6- متیل-4-پیریمیدین آمین (1) با هیدرازین هیدرات در حلال اتانول، 5-برومو-2-هیدرازینو -6-متیل -4-پیریمیدین آمین (2) به دست آمد. سپس از واکنش این ترکیب با تری اتیل اورتو استر های مختلف در حلال استیک اسید محصولات تری آزولوپیریمیدین (a,b3) حاصل گردید. همچنین از واکنش مشتق هیدرازین دار (2) با سدیم نیتریت در حلال استیک اسید و آب حد واسطی ایجاد شده است که از ر...
15 صفحه اولSynthesis and Biological Activity Evaluation of Novel Heterocyclic Pleuromutilin Derivatives.
A series of pleuromutilin derivatives were synthesized by two synthetic procedures under mild reaction conditions and characterized by Nuclear Magnetic Resonance (NMR), Infrared Spectroscopy (IR), and High Resolution Mass Spectrometer (HRMS). Most of the derivatives with heterocyclic groups at the C-14 side of pleuromutilin exhibited excellent in vitro antibacterial activities against Staphyloc...
متن کاملSynthesis and Antibacterial Activity of Novel Curcumin Derivatives Containing Heterocyclic Moiety
A series of curcumin derivatives containing heterocyclic moiety have been synthesized and evaluated for their antibacterial activities. The chemical structures of the synthesized compounds were verified on the basis of spectral data and elemental analyses. Investigation of antimicrobial activity of the derivatives demonstrated the ability to inhibit Gram-positive microorganisms with zone of inh...
