Method for the synthesis of a molecular lasso structure consisting of a cyclic moiety and of a linear moiety, wherein the linear moiety is covalently attached to the cyclic moiety and with its free end is partially threaded through the orifice formed by the cyclic moiety, including the following steps, preferably in given order: ) provision of a cyclic moiety and of a first linear structural element and establishing conditions in which at least a fraction of the first linear structural element is threaded through the orifice of the cyclic moiety; 2) covalently attaching a stopper element preventing de-threading of the first linear structural element to one terminal end of the first linear structural element; 3) separating unthreaded cyclic moieties and first linear structural elements from threaded molecular assemblies, in which threaded molecular assemblies the first linear structural element with said stopper element is threaded through the cyclic moiety, by chemical and/or physical separation and using essentially only the threaded molecular assemblies for further reaction; 4) reacting the threaded molecular assemblies with a bifunctional second linear structural element so that the second linear structural element is covalently attached to the first linear structural element at or close to its end opposite to the end where the stopper is attached, and so that the second linear structural element is covalently attached to the cyclic moiety.
合成分子套索结构的方法,包括一个环状部分和一个线性部分,其中线性部分与环状部分共价连接,并且其自由端部分部分穿过环状部分形成的孔,包括以下步骤,最好按照给定的顺序进行:1)提供一个环状部分和一个第一线性结构元素,并建立条件,使第一线性结构元素的至少一部分穿过环状部分的孔;2)将阻止解开第一线性结构元素的阻塞元素共价连接到第一线性结构元素的一个末端;3)通过化学和/或物理分离,将未穿过的环状部分和第一线性结构元素与穿过的分子组装体分离开来,并且仅使用穿过的分子组装体进行进一步反应;4)将穿过的分子组装体与双功能第二线性结构元素反应,使第二线性结构元素共价连接到第一线性结构元素的末端或接近末端,其中阻塞元素连接的另一端,并且使第二线性结构元素共价连接到环状部分。
