Derivatives of the macrocyclic polyether dibenzo-18-crown-6 containing tetrazol-1-yl and 5-methyltetrazol-1-yl substituents in one of the phenyl rings have been synthesized for the first time: 1-(6,7,9,10,17,18,20,21-octahydrodibenzo[b,k][1,4,7,10,13,16]hexaoxacyclooctadecen-2-yl)-1H-tetrazole and 5-methyl-1-(6,7,9,10,17,18,20,21-octahydrodibenzo[b,k][1,4,7,10,13,16]hexaoxacyclooctadecen-2-yl)-1H-tetrazole
首次合成了在一个苯环中包含四唑-1-基和5-甲基四唑-1-基取代基的大环聚醚二苯并-18-crown-6的衍生物:1-(6,7,9, 10,17,18,20,21-八氢二苯并[ b,k ] [1,4,7,10,13,16]六氧环环十八烯-2-基)-1 H-四唑和5-甲基-1-(6, 7,9,10,17,18,20,21-八氢二苯并[ b,k ] [1,4,7,10,13,16]六氧环十八烷基-2-基)-1 H-四唑。通过三组分多米诺反应获得第一化合物,该反应包括在冰乙酸中的二苯并-18-冠-6的芳基氨基衍生物,原甲酸三乙酯和叠氮化钠。第二种化合物是通过在乙腈中用四氯硅烷-叠氮化钠体系处理适当的乙酰胺来制备的。
