摘要： 以L-薄荷醇、氯化亚砜、4-甲基噻唑等为原料，设计合成出一类新型的噻唑基手性离子液体催化剂，并将其用于催化肉桂醛的自身缩合反应生成γ-丁内酯。实验结果表明，在手性离子液体的催化下，主要得到顺式γ-丁内酯产物。对影响反应的各种因素进行了详细的考察，在较佳的条件下，γ-丁内酯的收率为45.8%。考察了离子液体催化剂的循环使用效果，催化剂可重复使用4次，其催化活性基本不变。

Abstract: The novel thiazolium chiral ionic liquids were synthesized from L-menthol, thionyl chloride and 4-methylthiazole. The new ionic liquids were used for catalyzing the self-condensation of cinnamaldehyde to synthesize γ-butyrolactone. The experiments results showed the main product was trans-butyrolactone. The effect of reaction conditions on the reaction was fully investigated. Under the optimal conditions, the yield of γ-butyrolactone was 45.8%. The recycling efficiency of ionic liquids catalyst was also investigated. The catalyst could be recycled 4 times, and the catalytic activity kept constant.
Key words: thiazolium chiral ionic liquids; cinnamaldehyde; γ-butyrolactone
