INTRAMOLECULAR CYCLIZATIONS OF HANTZSCH 1,4-DIHYDROPYRIDINES: SYNTHESIS OF DI- AND TETRAHYDROINDENOPYRIDINES

Hantzsch 4-phenyl-1,4-dihydropyridines bearing electrophilic ortho substituents react with trimethylsilyl cyanide/zinc iodide or base resulting in an intramolecular cyclization reaction to give di-and tetrahydroindenopyridines in good yield.
