提出了一种改进的水溶性深腔空化试剂(辛酸,1)的合成方法。以前(Gibb,C.L.D.和Gibb,B.C.,J.Am化学。Soc.,2004,126,11408-11409),我们记录了从间苯二酚开始以八个(非线性)步骤访问主机1;一个合成需要四个步骤,包括层析纯化。在这里,我们揭示了一种改进的主体1的合成。这种新的合成包括七个(非线性)步骤,只涉及一个层析步骤,并且避免了原始方法中观察到的少量杂质。因此,这种改进的合成将对研究这些类型宿主的性质的实验室有用。
An improved synthesis of a water-soluble deep-cavity cavitand (octa-acid, 1) is presented. Previously (Gibb, C. L. D. & Gibb, B. C., J. Am. Chem. Soc., 2004, 126, 11408–11409) we documented access to host 1 in eight (non-linear) steps starting from resorcinol; a synthesis that required four steps involving chromatographic purification. Here we reveal a modified synthesis of host 1. Consisting of seven (non-linear) steps, this new synthesis involves only one chromatographic step, and avoids a minor impurity observed in the original approach. This improved synthesis will therefore be useful for the laboratories that are investigating the properties of these types of host.
