A novel Schiff base was synthesized by the reaction of piperonal and anthranilic acid, which was further utilized in the synthesis of five novel complexes by reaction with different metal salts ultrasonically. Time for the reaction was greatly reduced through ultrasound irradiations and the yield of reactions was also high as compared to the conventional methods using reflux conditions. The...

Vanadium (III) gives a greenish- yellow complex with anthranilic acid in presence of pyridine. The complex is extractable with chloroform and is used for photometric determination of vanadium by measuring the absorbance at 390 nm against a reagent blank. Beer's Law holds good in the range of 1-20 pg V/ml. Moderate amounts of Pb (II) , Ca (II) , Sr (II) , Ba (II) , Cd (II) , Mg (II) , Mn (II...

2-[2-(2,6-Dichlorophenyl)amino]phenylmethyl-3-{4-[(substituted phenyl)amino]-1,3-oxazol-2-yl)-7-chloroquinazolin-4(3H)ones 5a-o have been prepared from 2-[(2,6-dichloro phenyl)amino]phenyl acetic acid 1, which was converted to acid chloride 2 and cyclized with anthranilic acid afforded benzoxazin-4(H)ones 3. Further reaction with urea gave carboxamide-7-chloroquinazolin-4(3H)ones 4 cyclized wit...

Paper chromatography has provided an excellent method for the detection and identification of tryptophan and its fluorescing metabolites (1) and has proved helpful in the development of methods for the quantitative calorimetric estimation of tryptophan, kynurenine, and anthranilic acid (2). The purpose of this communication is to report the use of these techniques in determining the effect of a...

Abstract We report the first total synthesis of an antimycobacterial natural product oxazinin A that takes advantage a multi‐component cascade reaction anthranilic acid and precursor polyketide containing aldehyde. The route utilized for pseudodimeric validates previously proposed biosynthetic mechanism, invoking non‐enzymatic pathway to complex molecule. found 76 : 10 9 5 ratio diastereomers f...

Understanding the interaction of carboxylic group with TiO2 is crucial for photocatalytic degradation pollutants, because aromatic molecules containing acid groups are among most common micropollutants. This study investigated interactions anatase (101) surface several acids: benzoic, nicotinic, salicylic and anthranilic acid, using dispersion-corrected density functional theory (DFT) calculati...
