(Hetero)aryl, benzylic, and alkyl zinc halides were thiolated with N‐thiophthalimides at 25 °C within 1 h in the presence of 5–10 % Cu(OAc)2⋅H2O to furnish the corresponding polyfunctionalized thioethers in good yields. This electrophilic thiolation was extended to the introduction of trifluoromethylthio (SCF3), thiocyanate (SCN), and selenophenyl (SePh) groups. The utility of this method was shown
(杂)芳基,苄基,和烷基卤化锌用硫醇化Ñ -thiophthalimides在25℃下在5-10%的Cu的存在下在1个小时内(OAC)2 ⋅ ħ 2 O操作提供以良好的收率相应多官能硫醚。该亲电子硫醇化作用扩展到引入三氟甲硫基(SCF 3),硫氰酸酯(SCN)和硒代苯基(SePh)基团。该方法的效用在有效的组织蛋白酶D抑制剂的七步合成中得到了证明,总产率为34%。
