copper-mediated synthesis of diaryl sulfides utilizing Cu(I)-thiophene-2-carboxylate (CuTC) is described. We demonstrate the use of CuTC as a soluble, non-basic catalyst in the coupling of aryl iodides and aryl thiols in the synthesis of synthetically advanced diaryl sulfides. This method allows for the successful coupling of challenging substrates including ortho-substituted and heteroaryl iodides and thiols
描述了利用Cu(I)-噻吩-2-羧酸盐(CuTC)的铜介导的二芳基硫醚的合成。我们证明了在合成高级二芳基硫醚的合成中,CuTC作为可溶性,非碱性催化剂在芳基碘化物和芳基硫醇的偶联中的应用。这种方法可以成功地耦合包括邻位在内的具有挑战性的基材-取代的和杂芳基碘化物和硫醇。另外,这里使用的大多数芳基碘化物底物包含与嘧啶,吡啶或苯环键合的特权哌嗪支架,因此该方法允许将复杂的哌嗪支架加工成具有生物学意义的分子。此处描述的方法可以将后期结构的多样性纳入到含有哌嗪环的二芳基硫醚中,从而提高了可用于SAR研究的衍生物的数量和性质。
