  Comparison of diffusion coefficients for matched pairs of macrocyclic and linear molecules over a drug-like molecular weight range

  摘要：

  通过核磁共振波谱法比较了一系列紧密匹配的大环和线性分子对的扩散系数。大环系列的设计既与通常用于类药物分子的分子量范围重叠，又有所扩展。每个线性分子代表了其相应大环分子的碳解裂变，旨在最小化功能和物理化学性质的差异。每个分子系列均采用铜催化的叠氮-炔环加成（CuAAC）反应，在流动体系中使用铜管进行制备。在整个研究分子量范围内，大环系列始终展现出更高的扩散性。大环和线性类似物之间扩散系数的倍数差异似乎与溶剂粘度或介电环境无关。

  of 12‐ to 22‐membered macrocycles, with druglike functionality and properties, have been generated by using a simple and efficient copper‐catalyzed azide–acetylene cycloaddition reaction, conducted in flow in high‐temperature copper tubing, under environmentally friendly conditions. The triazole‐containing macrocycles have been generated in up to 90 % yield in a 5 min reaction, without resorting to

• Strained Cyclophane Macrocycles: Impact of Progressive Ring Size Reduction on Synthesis and Structure
  作者：Andrew R. Bogdan、Steven V. Jerome、K. N. Houk、Keith James

  日期：2012.2.1

  The synthesis, X-ray, crystal structures, and calculated strain energies are reported for a homologous series of 11- to 14-membered drug-like cyclophane macrocycles, representing an unusual region of chemical space that can be difficult to access synthetically. The ratio of macrocycle to dimer, generated via a copper catalyzed azide-alkyne cycloaddition macrocyclization in flow at elevated temperature, could be rationalized in terms of the strain energy in the macrocyclic product. The progressive increase in strain resulting from reduction in macrocycle ring size, or the introduction of additional conformational constraints, results in marked deviations from typical geometries. These strained cyclophane macrocyclic systems provide access to spatial orientations of functionality that would not be readily available in unstrained or acyclic analogs. The most strained system prepared represents the first report of an 11-membered cyclophane containing a 1,4-disubstituted 1,2,3-triazole ring and establishes a limit to the ring strain that can be generated using this macrocycle synthesis methodology.
