Four novel chiral quaternary ammonium salts were synthesized from naturally occurring rosin. These compounds were employed as phase-transfer catalysts in asymmetric epoxidation reactions of chalcone, affording the corresponding epoxides in high yields and up to 20% ee.

Key words: rosin, asymmetric epoxidation, quaternary ammonium salt, chalcone, chiral phase-transfer catalyst
