| titleOfInvention | Process for producing chromone compound |
| abstract | A process for producing a dicarboxylic acid compoundnrepresented by the formula (4):n nwherein R 1 and R 2 are the same or different and eachnrepresents lower alkyl and the wavy line indicates thatnthis compound is the E- or Z-isomer or a mixture of them,ncharacterized by reacting a compound represented by thenformula (2):n nwherein R 1 , R 2 and the wavy line have the same meanings asnthe above, and one of X 2 and X 3 represents hydrogen and thenother represents halogen, with nitrophenol represented bynthe formula (3):n nin the presence of a base; a process for producing annitrochromone compound represented by the formula (5): n nwherein R 1 has the same meaning as the above, characterizednby reacting the dicarboxylic acid compound or carboxylicnacid thereof with an acid; a process for producing annaminochromone compound which comprises reducing thennitrochromone compound; and a process for producing annamidochromone compound which comprises acylating thenaminochromone compound are provided. |
