10 mol% of phase-transfer, PT catalysts in water. Some chiralquaternaryammonium salts derived from Cinchona alkaloids were investigated as water-stable PT catalysts. The scope and limitations of the reaction have also been investigated. The catalytic performances were significantly improved in comparison with the corresponding ordinary quaternaryammoniumsaltcatalysts, and excellent yields (81%–96%)
