描述了能够与胺和羧酸都结合的分子的合成。该新宿主由具有带有乙酰氨基吡啶部分的侧臂的吡咯并异喹啉结构组成。吡咯并异喹啉部分是在改进先前公开的途径之后获得的,该途径包括适当的3-芳基烷基氨基琥珀酰亚胺的区域选择性还原,然后使用亚胺鎓化学进行闭环。然后在Pd 0下通过交叉偶联反应将三环结构官能化乙酸甲酯的三甲基甲硅烷基烯酮缩醛催化三氟甲磺酸酯衍生物。然后将如此获得的酯与2-氨基-4,6-二甲基吡啶反应,产生目标宿主。后一种化合物与某些羧酸和胺的缔合常数通过1 H NMR滴定确定。进行了NOESY实验和分子模型计算,以便精确地进行实际的主客体相互作用。
The synthesis of novel pyrrolo[3,2-c]isoquinolines is investigated starting from 3-aminosuccinimides. Various known routes leading to 3-aminosuccinimides were tested but a new approach via nucleophilic addition of arylalkylamines on maleimide gave better results. The regioselectivity of the reduction of these compounds was shown to depend on the degree of substitution of the concerned 3-aminosuccinimide
functionalized by cross-coupling reaction under Pd0 catalysis of its triflate derivative with the trimethylsilyl ketene acetal of methyl acetate. The so-obtained ester was then reacted with 2-amino-4,6-dimethylpyridine leading to the targeted host. The association constants of this latter compound with some carboxylic acids and amines were determined by 1H NMR titration. NOESY experiments and molecular modeling
