Synthesis and antimicrobial activity of some new Mannich base derivatives
A series of new mannich base derivatives 4-(furan-2-yl(2-(furan-2-yl methylene)hydrazinyl)methyl)morpholine(1-6) were synthesized and synthesized compounds (16) were confirmed by IR, 1H NMR, 13C NMR, Mass spectral, mass spectral fragmentation and elemental analysis. Synthesized compounds (1-6) were screened for antimicrobial activity. Structural activity relationship has been discussed in this ...
متن کاملSynthesis, 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 Antimicrobial Studies of Some Novel Mannich Bases Derived from Secondary Amines
The amino alkylation of aromatic substrates by the Mannich reaction is of considerable importance for the synthesis and modification of biologically active compounds. The Mannich derivatives of 2-Chloro 4nitrobenzamide with formaldehyde and various secondary amines were synthesized for study of their biological effects. The structures of the synthesized compounds were assigned on the basis of e...
متن کاملDiastereoselective Synthesis of Stable Phosphorus Yields by a Three-Component Reaction between Ph3P and Acetylenic Esters in the Presence of Hydrazine Derivatives
In this work, stable crystalline phosphorus yields are obtained in good yields from the 1:1:1 addition reactions between hydrazine derivatives and dialkyl acetylenedicarboxylates in the presence of triphenylphosphine at room temperature in dichloromethane. This synthetic method has merits of high yields, mild reaction conditions, and simple experimental and work-up conditions. The obtained yiel...
متن کاملsynthesis 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...
