摘　　要：以天然松香为原料合成了4个新型手性季铵盐类相转移催化剂,并用于催化不对称查尔酮环氧化反应,发现这类手性相转移催化剂可以有效地催化查尔酮的不对称环氧化,环氧化产物ee最高达20%.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.
