A short and efficient regioselective synthesis of a number of 1,4-disubstituted-1,2,3-triazole derivatives of oxindoles from N-terminal alkyne and alkynyl ether derivatives of Morita-Baylis-Hillman (MBH) adducts of isatin with in situ generated alkyl azide and copper(I) iodide as a catalyst in 1:1 mixture of t-BuOH:water as a solvent system has been achieved. The synthetic procedure tolerates most
短程有效的区域选择性合成靛红的N,-末端炔烃和炔基醚衍生物的Isatin的Morita-Baylis-Hillman(MBH)加合物与原位的吲哚的许多1,4-二取代-1,2,3-三唑衍生物在叔丁醇:水为溶剂体系的1:1混合物中生成了叠氮化物和碘化亚铜(I)作为催化剂。合成方法可耐受MBH加合物中存在的大多数官能团,并避免了与潜在毒性和爆炸性有机叠氮化物的分离有关的问题。J.杂环化学,(2009)。
