straightforward synthesis of C2-symmetric azole-containing macrocyclic peptides is presented. This type of macrocycle possesses four amide groups directed into the interior of the scaffold that act as hydrogen-bond donors and two nitrogen atoms from the azole unit that act as hydrogen-bond acceptors. This arrangement makes them sensitive receptors for Y-shaped anions like AcO– and H2PO4– with a selectivity for dihydrogen
提出了一种直接合成 C2 对称的含唑类大环肽。这种类型的大环具有四个直接进入支架内部的酰胺基团,作为氢键供体和来自唑单元的两个氮原子,作为氢键受体。这种排列使它们成为 Y 型阴离子(如 AcO– 和 H2PO4–)的敏感受体,对磷酸二氢盐与乙酸盐具有选择性,如 [D6]DMSO/5% CDCl3 中的 1H NMR 滴定技术所示。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
