Different 3,6-dichloropyridazine-cinchona alkaloid derivatives have been used to catalyze the asymmetric “interrupted” Feist-Bénary reaction of β-dicarbonyl compounds with ethyl bromopyruvate/substituted β-bromo-α-bromoketoesters. The corresponding hydroxydihy-drofurans have been obtained in high yields (72%～97%) and with up to 93% ee.
Key words: asymmetric “Interrupted” Feist-Bénary reaction, 3,6-dichloropyridazine-cinchona alkaloid derivative, furan compound
