概要

• 論文の詳細を見る

• Michael condensation of 2-methylsulfinylmethyl-1,3-dicarbonyl compounds (3) or 2-methylene-1,3-dicarbonyl compounds (4) with 4-hydroxycoumarin (5) at ambient temperature gave 2-[(4-hydroxycoumarin-3-yl)methyl]-1,3-dicarbonyl compounds (6). Treatment of 6 with methanolic hydrogen chloride resulted in the regioselective formation of 2,2,3-trisubstituted-3,4-dihydro-2H-pyrano[3,2-c][1]benzopyran-5-ones.
