Résumé                                                Symmetrical nitrogen containing ring structures with two or four glucose units were easily obtained from accessible monosaccharide building units. Various tetherings via 4,4’- and 6,6’-positions lead to a variety of precursors which were transformed successively employing different bridging units by Richman–Atkins cyclisation to result in defined glycophane coronands.

对称氮含量环结构及其包含两个或四个
葡萄糖单元的化合物可以容易地从可获得的
单糖构建单元中获得。通过4,4'-位和6,6'-位的各种连接方式,得到了各种前体,这些前体通过Richman–Atkins环化反应,采用不同的桥接单元连续转化,最终形成了明确的糖
芳烃冠醚。
