Fused heterocyclic compounds with alkyne substituent, have been achieved using a domino microwave-assisted [Pd]-catalysis. Interestingly, tert-propargyl alcohols underwent a selective degradative β-carbon cleavage and served as masked alkynyl equivalents, in water as the sole reaction medium. Dihydrobenzofurans, indolines, and oxindoles have been accomplished using this dual C–C bond-forming strategy.

炔丙醇作为炔烃源：微波辐射下杂环化合物的合成

使用多米诺骨牌微波辅助[Pd]催化已经实现了具有炔烃取代基的稠合杂环化合物。有趣的是，叔炔丙基醇在水中作为唯一的反应介质，经历了选择性的降解β-碳裂解，并作为掩蔽的炔基当量。使用这种双重CC键形成策略已经完成了二氢苯并呋喃，二氢吲哚和羟吲哚。
