Sequential Reduction

An efficient iron/acetic acid system-mediated reductive cyclization reaction of substituted 2-aryl-3-nitro-2H-chromenes with substituted 2-nitrobenzaldehydes for the synthesis of 6-aryl-6H-chromeno[3,4-b]quinolines was developed. This reaction involves the sequential reduction, hydrolysis, aldol condensation, intramolecular addition, and the nucleophilic addition of substituted 2-aryl-3-nitro-2H-chromenes with substituted 2-nitrobenzaldehydes to give the corresponding 6H-chromeno[3,4-b]quinolines. This transformation provides a straightforward synthetic protocol for constructing substituted 6H-chromeno[3,4-b]quinoline derivatives. The structures of three typical products were confirmed by X-ray crystallography.

Hydrolysis Of

o-Nitrophenylpyruvic acid thiosemicarbazone (I) has been cyclized to 2-thio-5-(o-nitrobenzyl)-6-azauracil (II) which has been transformed in 5-(o-nitrobenzyl)-6-azauracil (III) by both oxidation, and methylation and hydrolysis of the 3-methylmercapto-6-(o-nitrobenzyl)-2,5-dihydro-1,2,4-triazin-5-one (V) formed. Reduction of derivative III with iron(II) hydroxide and cyclization of the amino derivative IV formed gives 2,3,4,10-tetrahydro-1,2,4-triazino[5,6-b]quinolin-3-one (VI). Compound VI is transformed in acid medium to 1-amino-1,2-dihydroimidazo[4,5-b]quinolin-2-one (VIII) via the tautomer VII, and in boiling acetic acid it gives the acetylamino derivative IX. The N-amino derivative VIII reacts with carbonyl compounds to give the corresponding hydrazones X - XII, and its nitrosation gives 1,2-dihydroimidazo[4,5-b]quinolin-2-one (XIII).
