[摘要]:An efficient synthesis of novel aryl/heteroaryl-substituted thieno-fused heterocycles, that is, thieno[2,3-b]thiophenes, thieno[2,3-b]indoles, and pyrazolo[3,2-c]thiophenes, involving radical-mediated cyclization of 2-(2-bromoheteroaryl)-3-methylthio-3-aryl/heteroaryl acrylonitriles has been reported. |
