  Synthesis of Deuterium-Labeled Cryptophane-A and Investigation of Xe@Cryptophane Complexation Dynamics by 1D-EXSY NMR Experiments

  摘要：

  We present the synthesis of a series of deuterated cryptophanes 2-6 by a slightly modified procedure used for cryptophane-A. We show that for [Xe@cryptophane] complexes the use of variable-temperature one-dimensional 129Xe magnetization transfer (1D-EX-SY) allows the measurement of exchange rates. From these data the decomplexation activation energy Ea has been estimated to be 37.5+/-2 kJ mol(-1). The decomplexation activation enthalpy, deltaH(++) = 35.5+/-2 kJ mol(-1), and entropy, deltaS(++) = -60+/-5 J mol(-1) K(-1), have also been calculated. The calculated negative activation entropy suggests that the activated complex associated with decomplexation is conformationally more strained than the complex in its ground state.

  The new bis-cryptophanes 7–9 were prepared from cryptophanols 1–3 and illustrate the synthetic possibilities offered by the latter for the design of new host systems featuring the preparation of large supramolecular receptors and new polycryptophane bio-sensors for NMR imaging. Hosts 1–3 were obtained from the monoprotected cryptophanes 4–6 following a multi-step strategy. The complexation of xenon by the dissymmetrical bis-cryptophane 8 was studied by 129Xe NMR spectroscopy. At low temperature, a strong discrimination (Δδ = 1.16 ppm) of the encapsulated xenon guests inside the two cryptophane cavities was observed. The kinetic parameters for the complexation process were determined from 1D-EXSY 129Xe NMR experiments. The activation energy Ea = 39.0 ± 3 kJ mol−1 and associated parameters ΔH≠ = 37.0 ± 3 kJ mol−1 and ΔS≠ = −46.0 ± 10 kJ mol−1 K−1 are in agreement with the values determined for cryptophane-A and [D27]-cryptophane-A.

  新的双隐酚 7-9 由隐酚 1-3 制备而成，说明后者为设计新的宿主系统提供了合成的可能性，该系统的特点是制备大型超分子受体和用于 NMR 成像的新型聚隐酚生物传感器。宿主 1-3 是通过多步骤策略从单保护的加密货币 4-6 中获得的。通过 129Xe NMR 光谱研究了不对称双隐烷 8 与氙的络合作用。在低温下，观察到两个隐光子空腔内封装的氙客体具有很强的辨别力（Δδ = 1.16 ppm）。络合过程的动力学参数由 1D-EXSY 129Xe NMR 实验确定。活化能 Ea = 39.0 ± 3 kJ mol−1 和相关参数 ΔH≠ = 37.0 ± 3 kJ mol−1 和 ΔS≠ = −46.0 ± 10 kJ mol−1 K−1 与 Cryptophane 确定的值一致A和[D27]-cryptophane-A。
