Bisamides based on the azulene moiety were investigated as building blocks for anion receptors. In the course of these studies, derivatives of azulene-1,3- and -5,7-dicarboxylic acid were synthesized and thoroughly characterized. The anion affinities of the derivatives based on functionalization in the five-membered ring and in the seven-membered ring were determined by (1)H NMR titration. The structural
研究了基于z基部分的双酰胺作为阴离子受体的组成部分。在这些研究过程中,合成并详细表征了azulene-1,3-和-5,7-二羧酸衍生物。通过(1)1 H NMR滴定确定基于五元环和七元环中官能化的衍生物的阴离子亲和力。这些构件的结构分析是通过X射线衍射,分子建模和2D NMR光谱进行的。五元环衍生物易于获得,提供了以syn-syn构象预组织的结合位点,并以类似于基于吡咯的类似物的强度结合了阴离子。也有强有力的证据证明芳香族CH ...阴离子之间的相互作用。
