Effiecient Synthesis of tetrazoloquinoxaline derivatives
Displacement reaction of 2,3-dichloroquinoxaline with secondary amines in boiling ethanol afforded it`s mono aminoquinoxaline derivatives. Further reaction of the latter compounds with sodium azide in warm dimethylsulfoxide achieved a group of 4-amino tetrazolo[1,5-a]quinoxaline derivatives. 1HNMR spectra of these compounds are discussed.
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 of Curcumin Derivatives
In this paper the synthesis of curcumin and curcumin derivatives is realised, based on the condensation of benzaldehydes substituted by acetyl acetone. The synthesis way is described and the obtained products are characterised in terms of substituted benzaldehydes, colour, melting point and elemental composition.
متن کاملSynthesis of thiadiazine-3,7-diamine derivatives
New 1,5-tetra alkyl methyl- phenyl-1H-pyrimido[4,5-e][1,3,4]thiadiazine-3,7-diamine were synthesized via the cyclocondensation of 2-(5-bromo-2-chloro-6-methylpyrimidin-4-yl)-2-methylhydrazine with phenylthioisothiocyanate and further replacement of chlorine atom on the seven number position of pyrimido[4, 5- e][1, 3, 4]thiadiazin by appropriate secondary amines in simple and efficient methods.
متن کاملSynthesis of tunicaminyluracil derivatives.
A tunicaminyluracil derivative, which is a key component of the tunicamycin nucleoside antibiotics, was synthesized using a samarium diiodide (SmI2) mediated aldol reaction and intramolecular Pummerer reaction as the key steps. The alpha-phenylthio ketone 11, the precursor of the samarium enolate, was prepared from D-galactose. Treatment of 11 with SmI2 at -40 degrees C resulted in complete con...
