Our researches are included as follows: 1. N-( diphenylmethylene) glycine t-butyl ester was synthesized from benzophenone imine and t-butyl chloroacetate using microwave irradiation, and under the optimum conditions chemical yield gets 98%.

我们的研究工作主要包括以下几个方面：1.以二苯甲酮亚胺和α-氯代乙酸叔丁酯为原料，合成了二苯甲酮亚胺甘氨酸叔丁酯，在优化条件下，化学产率高达98%。
