posted on 2010-02-05, 00:00 authored by Tuan-jie Meng, Yimin Hu, Shaowu WangGeneral and efficient methods for the construction of five-membered aromatic and nonaromatic heterocycles by palladium-catalyzed coupling/cycloisomerization of 1,6-enynes and aryl halides have been developed. Results indicate that substituents at the terminus of the alkynes have a significant effect on the selective formation of the products.
