Synthesis 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 کاملMicrowave assisted synthesis of [4, 5-e] [1, 3, 4]thia- diazin-7-yl] hydrazine Derivatives
New pyrimido [4, 5-e] [1, 3, 4]thia- diazin-7-yl] hydrazines were synthesized via the cyclocondensation of alkyl-2-phenylhydrazinecarbodithioates as a binucleophile with 5-bromo-2,4-dichloro-6-methylpyrimidine as a bielectrophile , and replacement of C-7 chloro atom by hydrazine in ethanol as the solvent . This method has advantages over methods currently described in the literature for the con...
متن کاملSynthesis of Some New 1-[2-(alkylthio-1-benzyl-5-imidazolyl) carbonyl]-4-[3-(isopropylamino)-2-pyridyl] piperazines as Anti-HIV
A few analogues of atevirdine or 1-[(5-methoxyindol-2-yl) carbonyl]-4-[3- (ethylamino)-2-pyridyl] piperazine – an anti-HIV belonging to non-nucleoside reverse transcriptase inhibitors were synthesized and evaluated for anti-HIV activity. Replacement of indolyl moiety with 2-alkylthio-1-benzyl-5-imidazolyl substituent afforded 1-[2-(alkylthio-1-benzyl-5-imidazolyl) carbonyl]-4-[3-(isopropylamino...
متن کاملSYNTHESIS OF 4-(1-BENZYL-5-IMIDAZOLYL)-1,4-DIHYDROPYRIDINES
The o-nitrophenyl group at position 4 of dihydropyridine of nifedipine analogues was replaced with 2-alkylthio-1-benzyl-5-imidazolyl substituent. Starting from dihydroxyacetone 2-alkythio-1-benzyl- 5-formyl imidazole (3) was first synthesized which was subsequently used in synthesizing symmetrical (5a-f) and asymmetrical (6a,b) dihydropyridines. Primarily pharmacological studies of the title co...
متن کامل6 - ( 1 , 3 - Dihydroxy - 3 - phenylpropylidene ) - 5 - hydroxy - 2 , 2 , 4 - trimethylcyclohex - 4 - ene - 1 , 3 - dione
A novel compound involved in the aroma of the fruit Campomanesia lineatifolia was isolated; the structure was determined by spectroscopic methods, mainly 1D and 2D NMR.
