[ 1 ] - reaction of thiohydantoins and ethylbromopyruvate for Synthesis of imidazo[2,1-b]thiazole 3-carboxylate

Imidazo[2,1-b]thiazoles are obtaind in excellent yields from the addition reaction between thiohydantoin and ethylbromopyruvate. These imidazo[2,1-b]thiazoles in the presence of p-TSA in boiling toluene refluxed for 2.5 hours led to imidazo[2,1-b]thiazole-3-carboxylates in elimination reactions

[ 2 ] - Chemical Composition of the Essential Oil Salvia Officinal from Shiraz Greenhouse

The genus is distributed throughout the Old World and the Americas, with three distinct regions of diversity: Central and shake the limbs and topic in folk medicine. South America (approx. 500 species), Central Asia and Mediterranean (250 species), Eastern Asia (90 species)various species of the genus salvia are used as Disinfectants, Epileptics Autodigestion, Reduce blood sugar donor, Carminat...

[ 4 ] - A New synthesis of functionalized imidazo[2,1-b][1,3]thiazines with thiohydantoins, isocyanides and dialkyl acetylenedicarboxylates

The reaction of stoichiometric amounts of dialkyl acetylenedicarboxylates with alkyl isocyanides and 5,5-diaryl thiohydantoins in toluene and catalytic amount of p-TSA afforded imidazo[2,1-b][1,3]thiazines in good overall yields

[ 5 ] - Synthesis of imidazo[2,1-b]thiazole-3-carboxylate through the reaction of thiohydantoins and ethylbromopyruvate

Imidazo[2,1-b]thiazoles are obtaind in excellent yields from the addition reaction between thiohydantoin and ethylbromopyruvate. These imidazo[2,1-b]thiazoles in the presence of p-TSA in boiling toluene refluxed for 2.5 hours led to imidazo[2,1-b]thiazole-3-carboxylates in elimination reactions

[ 6 ] - Synthesis of Novel imidazo[2,1-b]thiazoles from thiohydantoins and Diethyl oxalate

Novel imidazo[2,1-b]thiazoles were synthesized in good yield via a mild reaction of thiophenytoin and diethyl oxalatein the presence of 10% mol p-TSA.

[ 7 ] - Chemoselective Reaction Between 5,5-Diarylhydantoins and Acetylenic Esters in the Presence of Trialkyl Phosphite

The adducts produced in the reaction between trialkyl phosphites and acetylenic esters were trapped by hydantoins to produce highly functionalized dialkyl 2-(2,5-dioxo-4,4-diphenylimidazolidin-1-yl) succinate in good yields.

[ 8 ] - An Efficient One-pot Synthesis of Dialkyl fumarates Mediated by inyltriphenylphosphonium Salt in the Intramolecular Wittig Reaction

An efficient three-component reaction of dialkyl acetylendicarboxylates and 2-Pyrrolidin in the presence of triphenylphosphine produces dialkyl 2-(2-Pyrrolidin-N-yl)-3-(triphenylphosphanylidene)succinate. These phosphoranes undergo mild intramolecular Wittig reaction to produce dialkyl (E)-2-(4,5-dihydro-3H-pyrrol-2-yl)fumarate in excellent yields.

[ 9 ] - تأثیر باران‌های اسیدی بر روی محیط زیست و آثار باستانی تخت‌جمشید

با توجه به تخریب سنگ‌های منطقه‌ی باستانی تخت‌جمشید تصمیم گرفته شد تا عوامل مؤثر بر این فرایند بررسی شود. این تحقیق با مطالعهی نقشه‌های جغرافیایی و نمودار بادهای فصلی و سالیانه منطقه و همچنین نمونه‌گیری از آب باران پیگیری شد. نمونه‌گیری آبهای‌ مختلف از مکان‌های متفاوت و مشخص شهرستان مرودشت در زمان‌های معین در سه فصل پاییز، زمستان و بهار به منظور اندازه‌گیری اسیدیته‌ی آب‌ها انجام شد. pH نمونهه...
