Abstract
Abstract The readily synthesized 3-(4-Hydroxy-1-methyl-1,2-dihydro-2-oxoquinolin-3-yl)-1-phenyl-1H-pyrazole-4-carbaldehyd (5) and 3-(2-Oxo-2H-chromen-3-yl)-1-phenyl-1H-pyrazole-4-carbaldehyde (6) were utilized as a convenient starting precursor materials for synthesis of novel enone system 4-hydroxy-1-methyl-3-(4-(2H-2-oxo-chromen-3-yl)prop-2-enoyl)-1-phenyl-1H-pyrazol-4-yl)quinolin-2(1H)-one (7) and4-hydroxy-1-methyl-3-(2E)-3-(3-(2-oxo-2H-chromen-3-yl)-1-phenyl-1H-pyrazol-4-yl)acryloyl)quinolin-2(1H)-one (8). Simple homonuclear NOE experiment (NOESY 1D) method was performed for structure elucidation of the novel quinolinyl chalcones. The synthesized compounds have been estimated for their effect of growth on some selective crop of plants (Hibiscus, Mint and Basil).
