A convenient synthesis of monosubstituted 3-alkynyl-furans by Suzuki coupling reaction of 3-furanylboronic acid with substituted acetylene bromides is described. The internal alkyne products were attainable in 50-89% yields from substrates free of relatively acidic protons. Our protocol is expected to find applications in the synthesis of structurally related natural products.
描述了通过 3-呋喃基硼酸与取代的溴乙炔的 Suzuki 偶联反应方便地合成单取代的 3-炔基-呋喃。从不含相对酸性质子的底物中,可以以 50-89% 的产率获得内部炔烃产物。我们的协议有望在结构相关的天然产物的合成中找到应用。
