synthesis and characterization of some macrocyclic schiff bases
ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
15 صفحه اولSynthesis, characterization and antimicrobial evaluation of some new schiff, mannich and acetylenic Mannich bases incorporating a 1,2,4-triazole nucleus.
A series of Schiff and Mannich bases derived from 4-amino-5-(3-fluoro-phenyl)-2,4-dihydro-3H-1,2,4-triazole-3-thione were synthesized. The alkylation of 4-phenyl-5-(3-fluorophenyl)-2,4-dihydro-3H-1,2,4-triazole-3-thione with propargyl bromide afforded the corresponding thiopropargylated derivative which upon treatment with the appropriate secondary amines in the presence of CuCl2 furnished the ...
متن کاملSynthesis and evaluation of anticonvulsant activities of some bis Mannich bases and corresponding piperidinols.
Some acetophenone derived bis Mannich bases (B1-B5) and piperidinols (C1, C4), which are the structural isomers of B1 and B4, and also quaternary piperidine derivative C6 were synthesized and studied for anticonvulsant activity. Of the compounds, C6 was reported for the first time. Chemical structures of the compounds were confirmed by UV, IR, 1H-NMR, 13C-NMR, mass spectra and elemental analysi...
متن کاملGreen Synthesis and Antihypertensive Activity of Some Mannich Bases of 1, 4 Dihydropyridine Compounds
Some new Mannich Bases of 1, 4 Dihydropyridine derivatives were synthesised by reaction of 1, 4 Dihydropyridine derivatives formaldehyde (HCHO) & secondary amines (e.g. morpholine, 1-methyl piperazine) in 1:1 ratio under acidic condition in presence of trace HCl. The compounds synthesised were identified by UV, 1H NMR, and FT-IR spectroscopic techniques. All compounds studied in this work were ...
متن کاملSYNTHESIS OF PARACETAMOL DERIVATIVES AS MANNICH BASES AND THEIR ANTIBACTERIAL ACTIVITY
Aim: A variety of Paracetamol derivatives as mannich bases were prepared through mannich reaction by reacting Paracetamol as compound containing active hydrogen, substituted benzaldehyde, morpholine as secondary amine compound and small amount of conc. HCl as catalyst. A simplistic one-pot method under mild conditions has been developed for the synthesis of all the compounds and they were chara...
