Aim: Dimedone , gamma pyrone and barbituric acid and their derivatives have also been found to be very important from their application point of view. Thus our aim was to prepare more derivatives from them. Method : Dimedone , gamma pyrone and barbituric acid have been treated with dimethyl sulphoxide and acetic anhydride reagent under varying temperature conditions in order to get more compoun...

Synthesis of 5-arylidine thiobarbituric acids containing different functional groups with variable electronic characters were described and their Co(2+), Ni(2+) and Cu(2+) complexes. The stereochemistry and mode of bonding of 5-(substituted benzylidine)-2-TBA complexes were achieved based on elemental analysis, spectral (UV-VIS, IR, (1)H NMR, MS), magnetic susceptibility and conductivity measur...

Abstract A set of C 3 N 4 samples has been prepared by using melamine, cyanuric acid and barbituric as the precursors. The materials were subjected both to physical chemical characterization used photocatalysts for selective oxidation aromatic alcohols in water suspension under UV visible irradiation. photoactivity versus partial four substituted benzyl was investigated. type position substitue...

A series of 5-benzylidenerhodanine-3-acetamides bearing morpholino-, 4-arylpiperazinyl-, or 4-benzylpiperidinyl- moieties were synthesized and their inhibitory activities against acetylcholinesterase (AChE) were evaluated. Alteration of amide part and substitution on the benzylidene moiety resulted in change of anti-AChE activity. The most active compound was the 1-benzylpiperidinyl derivative ...

The syntheses of calix[4]arene dimelamines that are functionalized with alkyl, aminoalkyl, ureido, pyridyl, carbohydrate, amino acid and peptide functionalities, and their self-assembly with barbituric acid or cyanuric acid derivatives into well-defined hydrogen-bonded nanostructures are described. The thermodynamic stability of these hydrogen-bonded assemblies was studied by CD spectroscopy in...

In the reaction of 5-arylidene-2,4-dioxothiazolidine-3-acetic acid chloride with 1,2,4-triazole, 1,2,4-triazoline-5-one and 1,2,4-triazoline-5-thione, the new corresponding 5-arylidene-2,4-dioxothiazolidine-3-acetic acid amides (5-16) were obtained. Compounds 6, 14 i 15 were investigated in vitro for their antioxidant activity.
