Vicarious nucleophilic substitution (VNS) of 3- and 4-nitro(pentafluorosulfanyl)benzenes with phenoxyacetonitrile followed by catalytic hydrogenation provided a two-step, atom-economical synthetic route to 6- and 5-(pentafluoro-sulfanyl)1 H indoles. The VNSreaction with chloromethyl phenyl sulfone, nitro group reduction, imine formation, and base-induced cyclization gave efficient access to 2-aryl
3-和4-硝基(五氟硫烷基)苯与苯氧基乙腈的替代亲核取代(VNS)随后催化氢化为6-和5-(五氟硫烷基)1 H吲哚提供了两步、原子经济的合成路线。VNS 与氯甲基苯砜、硝基还原、亚胺形成和碱诱导的环化反应可以有效地获得 2-芳基取代的 6-和 5-(五氟硫烷基)-1 H-吲哚。最后,VNS 与氯乙酸乙酯和硝基还原反应,然后进行热环化(内酰胺形成),得到含 SF 5 的羟吲哚。证明了它们转化为 2-卤代 SF 5 -吲哚。
