我们描述了一种杂化DNA/有机大环的合成,这种合成是通过在DNA的一个完整回合上形成酰胺键来制备的。链烷的形成证明了键是跨一个弯,而不是沿着磷酸二酯主链的轮廓。该产物是双尾链烷,包含5 ‘和3 ’端,可以进一步功能化或用于将链烷结构整合到其他DNA组装中。
We describe the synthesis of a hybrid DNA/organic macrocycle that is prepared by formation of an amide linkage across one full turn of DNA. Formation of a catenane proved that the linkage crossed a turn rather than running along the phosphodiester backbone contour. The product, a doubly tailed catenane, contains 5′- and 3′-termini that can be functionalized further or used to incorporate the catenane structure into other DNA assemblies.
