Disclosed herein is a novel method for preparing cyclophanes, comprising forming a disulfide cyclophane by contacting a linker moiety which includes two or more thiol groups, with a metal salt and an oxidant. The disulfide cyclophane is then desulfurized to form a thiacyclophane comprising thioether bridges. This thiacyclophane optionally may be further desulfurized to form an unsaturated hydrocarbon cyclophane, which can then be reduced to form a saturated hydrocarbon cyclophane. The various cyclophanes can be synthesized in a ring form, such as a dimer, trimer or tetramer etc., or they can be synthesized in a tetrahedral or larger structure. Also disclosed are novel cyclophanes formed by the disclosed method.
本文公开了一种制备环烷的新方法,该方法包括将包含两个或两个以上硫醇基团的连接分子与金属盐和氧化剂接触,形成二硫化环烷。然后将二硫化环烷脱硫,形成包含硫醚桥的硫代环烷。这种硫代环烷还可以进一步脱硫,形成不饱和烃环烷,然后再还原形成饱和烃环烷。各种环烷可合成为环状,如二聚体、三聚体或四聚体等,也可合成为四面体或更大的结构。同时公开的还有通过公开方法形成的新型环烷。
