A new derivative of the strained 3,3,6,6-tetramethylthiacycloheptyne (TMTH) bearing a functional handle is reported. Following an optimized synthesis, the handle was introduced by mild alkylation of the sulphur atom. The resulting functionalized strained 4,5-didehydro-3,3,6,6-tetramethyl-2,3,6,7-tetrahydrothiepinium (TMTI) proved to be stable and underwent extremely fast [3+2] cycloaddition reaction with benzyl azide in both organic and aqueous solvents. The reaction was equally efficient in cell lysate and serum and therefore opens interesting prospects for chemical-biology applications.
报道了一种新型应变3,3,6,6-四甲基硫杂环庚炔(TMTH)衍生物,其含有一个功能性手柄。经过优化的合成方法,通过硫原子的温和烷基化引入了该手柄。所得功能化的应变4,5-二脱氢-3,3,6,6-四甲基-2,3,6,7-四氢硫杂草镝(TMTI)表现出稳定性,并在有机和水性溶剂中与苄基叠氮化合物进行了极快的[3+2]环加成反应。该反应在细胞裂解液和血清中同样高效,因此为化学-生物学应用开辟了有趣的前景。
