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).

Schumacher and Halbsguth first demonstrated ectodesmata as pores or channels in the epidermal cell walls in haustoria of Cuscuta odorata L. by light microscopy in tissues fixed in a sublimate fixative (30% ethyl alcohol, 30 ml:glacial acetic acid, 10 ml: 65% nitric acid, 1 ml: 40% formaldehyde, 5 ml: oxalic acid, 2 g: mecuric chloride to saturation 2-3 g). Other workers have published electron micrographs of structures transversing the outer epidermal cell in thin sections of plant leaves that have been interpreted as ectodesmata. Such structures are evident following treatment with Hg++ or Ag+ salts and are only rarely observed by electron microscopy. If ectodesmata exist without such treatment, and are not artefacts, they would afford natural pathways of entry for applied foliar solutions and plant viruses.
