We describe herein a catalyst-free selective C−H sulfenylation of imidazo[1,2-a]pyridines using sulfonothioates as odorless source of thioarylated reagent in an aqueous medium. The method works for a variety of substituted imidazo[1,2-a]pyridines with broad functional group tolerance. The methodology has been extends to selective sulfernylation of indoles and imidazothiazoles. The sulfonothioates are
我们在本文中描述了咪唑并 [1,2-a] 吡啶的无催化剂选择性 CH 磺基化,使用硫代磺酸盐作为水性介质中硫代芳基化试剂的无味来源。该方法适用于具有广泛官能团耐受性的各种取代的咪唑并[1,2-a]吡啶。该方法已扩展到吲哚和咪唑并噻唑的选择性磺酰化。硫代磺酸盐仅在水介质而不是有机溶剂介质中被活化,并且已经证明了该方法用于放大研究的可行性。
