Abstract

This review describes the synthesis and chemical reactivity of tetrahydrothieno[3,2-b] quinoline derivatives through many reagents such as; 1, 2-dihydropyridine-3-carbonitrile; 1,6-dihydropyrimidine- 5-carbonitrile; 2,3-dihydropyridazine-4-carbonitrile; 3-amino-thiophene-2-carboxylate; 3- amino-thiophene-2-carbonitrile; 3,4-diaminothieno[2,3-b] thiophene-2,5-dicarbo- nitrile; 2-(3-bromo-1- iodoisoquinolin-8-yl) benzonitrile and 3-mercapto-benzo[g]quinolin-4(1H)-one derivatives. The synthesis of tetrahydrothieno [3, 2-b] quinoline derivatives was explained through the following chemical reactions: Aldol condensation, alkylation, cyclocondensation, dehydration, chlorination, Wolff-Kishner reduction, acylation, Friedlander reaction and intramolecular cyclization
Keywords: Pyridine-3-carbonitrile, pyrimidine-5-carbonitrile, 3-aminothiophene-2-carbonitrile, iodoisoquinolines, mercaptobenzoquinolinones, synthesis, reactivity
