To explore new synthetic methods, we set out a careful investigation of the reaction of benzimidazolium salt with many nucleophilic agents, including the active aromatic compounds and heteratom nucleophilic agents, and found that the quaternary C=N is not so active; when benzimidazolium salt is reacted with big nitrogen nucleophilic agent? phthalimide, it does not give the expected addition product, instead, produces N-alkyl phthalimide through alkyl-transfermation from benzimidazolium salt to phthalimide.

为了开发新的合成方法，研究了苯并咪唑盐与各种亲核试剂（活泼芳环与杂原子亲核试剂）的反应，发现苯并咪唑盐不与活泼芳环及杂原子亲核试剂发生2位加成反应；在与体积较大的位阻型N亲核试剂邻苯二甲酚亚胺反应时，未得到亲核试剂与极化的C＝N的加成产物，而是得到N烷基化的邻苯二甲酰亚胺，进一步研究表明，苯并咪唑盐将1（3）位N上的烷基转移给了邻苯二甲酰亚胺，并讨论了其反应机理和取代基，溶剂效应。

It was found that La〓 does not affect the binding affinity between calmodulin and Polistes Mastoparan, a known calmodulin binding peptide, neither the conformation of the ternary complex. Excessive amount of La〓 result in the decrease of the binding constant and the disrupted conformation. The binding affinity of La〓 to calmodulin increased in the ternary complex (La〓-CaM-Mas/Mas X), which suggested the coordination between the two global domains. The binding priority between the two global domains is also changed: La〓 more is likely to bind to the C-terminal of calmodulin than to N-terminal, thus facilitates the binding of Mas/Mas X to the C-terminal of calmodulin as the first step of the Mas/Mas X binding.

在以钙调蛋白结合肽—Polistes Mastoparan和Mastoparan X为对象的研究中，我们发现，除非过量，否则La〓的存在不影响钙调蛋白与Mas间的结合常数以及构象；过量的La〓（La〓/CaM摩尔比＞4）将引起钙调蛋白结合功能的下降，同时明显改变金属-钙调蛋白-Mas三元复合物的构象；La〓对Ca〓CaM-Mas的N末端表现高度选择性，显示了在三元复合物中两种离子间的协同效应；在三元体系中，La〓与钙调蛋白的亲和力明显上升，而且亲和力上升的程度因钙调蛋白结合肽的不同而有明显差异，显示了作用的选择性；Mas和MasX的存在改变了La〓在钙调蛋白上的结合顺序，La〓很可能优先与C末端结合，从而使Mas/Mas X首先与C末端结合，该顺序与钙离子相同；La〓的参与使三元复合物在动力学上更加稳定。
