Abstract

Keywords 2H-Pyrano[3,2-c]quinolin-2-one  (Z)-3-(4- (Chugger and Trivedi 1972). Other derivatives of 3 Oxo-1,4-dihydroquinolin-3-yl)-2-phenylacrylic acid  2- were prepared from 2,3-dihydroquinolin-4(1H)-one in Oxo-2H-pyrano[3,2-c]quinoline 6-oxide  Quinoline N- 72% yield (Peruncheralathan et al. 2004), from oxide  2H-Pyrano[3,2-c]-quinoline-2,5(6H)-dione  3-acetylquinolin-4(3H)-one in 70% yield (Ghorab et al. Cyclocondensation  Fluorescence 2001), from quinolin-4(1H)-ones or quinoline in 43% yield (Nesterova et al. 1995, 1993). Some of compounds 3 were prepared from substituted 4-hydroxyquinoline in 79% Introduction (Soliman and Said 1991), by hydrolysis of substituted 2H-pyrano[3,2-c]quinolin-2-ones (Thakore and Trivedi Synthesis and properties of 2H-pyrano[3,2-c]quinolin-2- 1980) or from derivatives of 4-hydroxyquinoline and ones 3 (Fig. 1) are described in the literature very insuffi- 4-hydroxyquinoline-3-carbaldehyde in 88 and 99% yield, ciently. Therefore, exploitations of 3 in life and material resp (Narasimhan and Bhagwat 1979). Even though sciences are very limited. The scientific database (The 4-hydroxyquinoline (quinolin-4-ol) and quinolin-4(1H)-one SciFinder 2017) has registered only 35 derivatives of 3, are tautomers, both structures (used separately) can be nineteen of them were prepared from 4-hydroxyquinolines found in the literature as a starting material.
