Application of Nicotinic Acid Functionalized Chlorosulfonic Acid as a Green Catalyst for the Synthesis of Bis(2-methyl-1Hindole)Derivatives
3-Carboxy-1-sulfopyridin-1-ium chloride ([CPySO3H]+Cl-) as a novel ionic organocatalyst for thecondensation of aldehydes and 2-methylindole to synthesize bis(2-methyl-1H-indole) derivatives inacetonitrile at room temperature has been developed. Some tetrakis (2-methyl-1H-indole)derivatives have also been synthesized by the reaction of 2,2'-(butane-1,4-diylbis(oxy))dibenzaldehyde and 2-methylind...
متن کاملSimultaneous spectrophotometric determination of trigonelline, diosgenin and nicotinic acid in dosage forms prepared from fenugreek seed extract
Mathematical algorithms offer a useful method for quantitative analysis of compounds in multi-component mixtures to overcome the overlapping problems occurred in UV spectrophotometry. The aim of this study is to develop a method to determine the bioactive compounds in herbal dosage forms produced from fenugreek extract. A UV- spectrophotometric method based on mathematical algorithm was used to...

متن کاملThe Quantitative Estimation of Nicotinic Acid in Animal Tissues
During the last few years the Konig reaction (1) between pyridine derivatives, cyanogen bromide, and aromatic amines has been made the basis of a number of procedures for the quantitative estimation of nicotinic acid in tissues. After extensive experience with several of these methods we have concluded that none is without severe defect and have attempted to formulate a more satisfactory proced...
