Abstract

Different modifications of the Hantzsch synthesis using 10-methyl-10H-phenothiazine-3-carbaldehyde gave 4-(10-methyl-10H-phenothiazin-3-yl)-substituted 1,4-dihydropyridine-3,5-di-, 5-oxo-4,5-dihydro-1H-indeno[1,2-b]pyridine-, and  5,5-dioxo-4,5-dihydro-1H-5λ<sup>6</sup>-benzo[4,5]thieno[3,2-b]pyridine-3-carboxylic esters.
