Hydrogenbond templated [2]catenanes and [2]rotaxanes have been synthesized using azide precursors derived from a single isophthalic acid derivative precursor. The interlocked molecules were prepared using either stoichiometric or near stoichiometric amounts of macrocycle and CuAAC “click” precursors, with yields of up to 70% for the mechanical bond formation step. Successful preparation of the interlocked
氢键模板化 [2] 链烷和 [2] 轮烷已使用衍生自单一间苯二甲酸衍生物前体的叠氮化物前体合成。使用化学计量或接近化学计量的大环化合物和 CuAAC“点击”前体制备互锁分子,机械键形成步骤的产率高达 70%。核磁共振光谱和质谱证实了互锁结构的成功制备,并通过一系列1 H NMR 光谱实验阐明了共构象行为的细节。
