乙二胺中2个氨基具有相同的反应活性,易同时反应形成对称的双Schiff碱,随着不对称配合物的设计和金属酶模型化合物的不断开发,业已发现严格控制反应条件和改变反应物摩尔比,可以有效地实现单个氨基的选择性反应,例如,在低温、稀的反应液中,乙酰丙 The two amino groups in ethylenediamine have the same reactivity and are easy to react simultaneously to form a symmetrical Schiff base. With the design of asymmetric complexes and the continuous development of metalloenzyme model compounds, it has been found that the reaction conditions are strictly controlled and the reactant Molar ratio, can effectively achieve the selective reaction of a single amino group, for example, in low temperature, dilute reaction solution,
