arylation of pyridylsulfides with good functional group tolerance was developed. To demonstrate synthetic utility, the resulting pyridylsulfonium salts were used in a scalable transition-metal-free coupling protocol, yielding functionalized bipyridines with extensive functional group tolerance. This modular methodology permits selective introduction of functional groups from commercially available pyridyl
开发了具有良好官能团耐受性的吡啶基硫醚的S选择性芳基化反应。为了证明其合成实用性,将所得吡啶基yl盐用于可扩展的无过渡金属偶联方案中,得到具有广泛官能团耐受性的官能化联吡啶。该模块化方法允许从可商购的吡啶基卤中选择性引入官能团,从而提供对称和不对称的2,2'-和2,3'-联吡啶。该方法的迭代应用使得能够合成具有三种不同吡啶组分的官能化的吡啶。
