Vicariousnucleophilic substitutions (VNS) of hydrogen in 1-nitro-4-(pentafluorosulfanyl)benzene with carbanions provide 2-substituted 1-nitro-4-(pentafluorosulfanyl)benzenes in good to high yields. VNS of 1-nitro-3-(pentafluorosulfanyl)benzene gives a mixture of 6- and 4-substituted 1-nitro-3-(pentafluorosulfanyl)benzenes in 85:15 to >98:2 ratio and good to high yields. In basic media, the VNS reactions

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。

Exploratory SAR studies of a new phenyl indole chemotype for p97 inhibition revealed C-5 indole substituent effects in the ADPGlo assay that did not fully correlate with either electronic or steric factors. A focused series of methoxy-, trifluoromethoxy-, methyl-, trifluoromethyl, pentafluorosulfanyl-, and nitro-analogues was found to exhibit IC(50)s from low nanomolar to double-digit micromolar. Surprisingly, we found that the trifluoromethoxy-analogue was biochemically a better match of the trifluoromethyl-substituted lead structure than a pentafluorosulfanyl-analogue. Moreover, in spite of their almost equivalent strongly electron-depleting effect on the indole core, pentafluorosulfanyl- and nitro-derivatives were found to exhibit a 430-fold difference in p97 inhibitory activities. Conversely, the electronically divergent C-5 methyl- and nitro-analogues both showed low nanomolar activities.
available 4-nitro-(pentafluorosulfanyl)benzene through vicariousnucleophilic substitution of hydrogen (VNS) reaction, reduction of nitro group and cyclization of resulting anilines were described. Transformations of 5-SF5-indazoles led to a variety of SF5-substiuted heteroarenes that can serve as a versatile building block for diversity-oriented organic synthesis.
