The first chemoselective direct dehydrative cross-coupling of tautomerizable heterocycles with alkynes has been achieved via C–H/C–OH bond activations with direct C(sp2)–C(sp) bond formation, which is in line with ideal synthesis using readily available materials.
首次实现了可互变异构的杂环与

化学选择性直接脱
水交叉偶联,通过C–H/C–OH键活化实现直接C(sp²)–C(sp)键的形成,这符合使用易得材料进行理想合成的原则。
