synthesis 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 اولFacile synthesis of 5, 6, 7, 8-tetrahydropyrimido [4, 5-b]-quinoline derivatives.
2-Amino-4-phenyl-5,6,7,8-tetrahydroquinoline-3-carbonitrile (3) was synthesized by treating cyclohexanone (1) with 2-benzylidenemalononitrile (2) in the presence of ammonium acetate. The reactivity of compound 3 towards dimethylformamide dimethyl acetal (DMF-DMA), carbon disulfide, urea, thiourea, formamide, formic acid, acetyl chloride and isothiocyanate were studied. In addition, the antimicr...
متن کاملSynthesis of new polyurethanes based on 5, 6, 7, 8 – tetrabromo – 2, 3 – dihydro – 1, 4 – phthalazine dione
In this work, 5,6,7,8-Tetrabromo-2,3-dihydro-2,3-bis(2-hydroxyethyl)phthalazine-1,4-dione is synthesized by the reaction of 5,6,7,8-tetrabromo-2,3-dihydrophthalazine-1,4-dione with 2-bromoethanol in the presence of triethylamine. The obtained monomer was polymerized with different diisocyanates, including hexamethylenediisocyanate (HMDI), tolylene-2,4-diisocyanate (TDI), isophoronediisocyanate ...
متن کاملSynthesis of Some Nitrogen Functional Derivatives of 5-substituted-6-azauracil as Biologically Active Compounds
3-Arylhydrazono-2,4-dioxo-4-phenylbutanoates have been prepared by the coupling of benzoylpyruvate with aryldiazonium chlorides. Reactions of the 3-arylhydrazono-2,4- dioxo-4-phenylbutanoates with 1-aminoguanidine, semicarbazide, and thiosemicarbazide gave 5-substituted 2-imino-6-azauracil (3a), 6-azauracil (3b), and 2-thio-6-azauracil (3c), respectively. The analytical data of these compounds ...
متن کاملSynthesis of Methyl 8-Cyanoheptafulvene-8-carboxylate Derivatives
Heptafulvenes, fundamental members of non-alternant conjugated compounds, are known to be stabilized by introduction of electron-withdrawing substituents on the C-8 position, e.g., 8,8-dicyanoheptafulvene (1).i' The bond lengths of the exocyclic C=C of the heptafulvenes have frequently been discussed as a measure of the contribution of a dipolar form.') For example, the exocyclic C=C bond lengt...
