prepared by an efficient one-step condensation of dipropargylglycoluril with formaldehyde under microwave irradiation. Their functionalization by click chemistry (CuAAC) afforded new multivalent architectures decorated with 8 or 12 ligands. Grafting of glycosides provided water-soluble glycobambus[4,6]uril platforms with glucosyl12BU[6] showing good affinity toward iodide anion in aqueous medium.
在微波辐射下,二炔丙基甘脲与甲醛的高效一步缩合反应制备了炔丙基化的bambus [4,6]脲。通过点击化学(CuAAC)对它们的功能化提供了新的由8或12个配体修饰的多价结构。糖苷的接枝提供了具有糖基12 BU [6]的水溶性糖尿[4,6] uril平台,对水性介质中的碘阴离子表现出良好的亲和力。
