SYNTHESIS AND ANTIRADICAL ACTIVITY OF 5-ACETYL-2-ALKYLTHIO-4-ARYL-6-METHYL-1,4-DIHYDROPYRIDINE-3-CARBOXYLIC ACID NITRILES
Keywords:
1,4-dihydropyridines, 1,1-diphenyl-2-picrylhydrazyl, radical cation, trolox, antiradical activityAbstract
The alkylation of 3-cyano-1,4-dihydropyridine-2(3H)-thiones or the condensation of an aromatic aldehyde, cyanothioacetamide, acetylacetone, and methyl iodide in the presence of piperidine has given a series of novel 5-acetyl-2-alkylthio-4-aryl-6-methyl-1,4-dihydropyridine-3-carboxylic acid nitriles. A compound was obtained from 3,5-di(tert-butyl)-4-hydroxybenzaldehyde in the molecule of which were combined the active part of the antioxidant ionol and a 1,4-dihydropyridine ring. It was found that, among the compounds synthesized, the highest antiradical activity occurred in a compound having two hydroxyl groups in the 4-phenyl substituent.
