A series of N’, N’’-[1-(1H-benzimidazole-2-yl)-2-(4-substituted phenyl ethane-1, 2-diyl)] substituted aromatic amines (AK1AK6) and hydrazides (AKH6 – AKH11) were synthesized by treating 2-methyl benzimidazole with different substituted aromatic aldehydes in the presence of ethanol to produce 2-[2-(4 chlorophenyl)-vinyl]-1H-benzimidazole. It was brominated to 2-[1, 2 dibromo 2-(4-substituted phe...

A method was proposed for the synthesis of substituted 2-(2-(furan-2-carbonyl)hydrazono)-4-oxobutanoic acids by reaction 2,4-dioxobut-2-enoic with furan-2-carbohydrazide. It found that undergo intramolecular cyclization in presence propionic anhydride to form corresponding N'-(2-oxofuran-3(2H)-ylidene)furan-2-carbohydrazides. The anti-inflammatory activity obtained compounds studied. have prono...

New novel derivatives of N-((5-((6-oxido-6-(4 substituted phenoxy)-4,8-dihydro-1H-[1,3,2] dioxaphosphepino [5,6-c]pyrazol-1-yl) methyl)-1,3,4-thiadiazol-2-yl)carbamoyl) substituted benzene sulfo namides (7a-o as depicted in scheme) were Synthesized by condensation reaction of 4substituted Phenyl phosphorodichloridates (6a-c) and N-((5-((4,5-bis(hydroxymethyl)-1H-pyrazol-1-yi)methyl)1,3,4-thiadi...
