Microwave-assisted synthesis and biological evaluation of some benzimidazole derivatives containing a 1,2,4-triazol ring
(Wiley-V C H Verlag Gmbh, 2013)
A new series of 2-(4-(trifluoromethyl)phenyl)-1H-benzo[d]imidazole derivatives containing a 1,2,4-triazole ring were synthesized via microwave technique. This efficient procedure provides pure products within a few minutes. ...
Design, synthesis and biological activities of some 7-aminocephalosporanic acid derivatives
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2013)
The treatment of 7-ACA with 4-substituted benzensulfonyl chlorides afforded the compounds containing 4-nitro/aminophenyl sulfonylamino moiety in the cephalosporanic acid skeleton (2, 4). the synthesis of the cephalosporanic ...
Microwave assisted synthesis of some hybrid molecules derived from norfloxacin and investigation of their biological activities
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2013)
Norfloxacin was converted to 7-(4-amino-2-fluorophenyl)piperazin derivative (2) via the formation of nitro compound. the synthesis of the norfloxacin derivatives containing 1,3-thiazole or 1,3-thiazolidin moiety was performed ...
An efficient synthesis of benzimidazoles via a microwave technique and evaluation of their biological activities
(Springer Wien, 2013)
A simple and practical protocol was developed for the synthesis of benzimidazoles. the protocol uses iminoester hydrochloride which is very useful in the reaction with 4,5-dichloro-1,2-phenylenediamine under microwave ...
Synthesis of some new 1,2,4-triazole derivatives starting from 3-(4-chlorophenyl)-5-(4-methoxybenzyl)-4H-1,2,4-triazol with anti-lipase and anti-urease activities
(Wiley-V C H Verlag Gmbh, 2014)
In the present study, starting compound 4 was prepared by deamination of compound 2 in the presence of hypophosphorous acid and sodium nitrite. Treatment of compound 4 with ethyl bromoacetate produced ethyl[3-(4-chloroph ...
Rapid synthesis and lipase inhibition activity of some new benzimidazole and perimidine derivatives
(Maik Nauka/Interperiodica/Springer, 2014)
This study presents a synthesis of new series of some benzimidazole, bisbenzimidazole and perimidine derivatives via microwave technique, which, leads to the good product yields and short reaction times. the structure of ...
Synthesis of some new hybride molecules containing several azole moieties and investigation of their biological activities
(Maik Nauka/Interperiodica/Springer, 2014)
1,2,4-Triazole-3-one prepared from tryptamine was converted to the corresponding carbothioamides by several steps. Their treatment with ethyl bromoacetate or 4-chlorophenacyl bromide produced the corresponding 5-oxo-1,3- ...
Microwave-promoted synthesis and biological activity of some 2-hetarylmethyl-4-(4-hetarylphenyl)-5-methyl-2,4-dihydro-3H-1,2,4-triazol-3-one derivatives
(Springer, 2015)
A series of fused and non-fused 1,2,4-triazole derivatives were prepared starting from ethyl 4-[1-(2-ethoxy-2-oxoethyl)-3-methyl-5-oxo-1,5-dihydro-4H-1,2,4-triazol-4-yl]benzoate. Firstly, both ethyl ester groups were ...
