of a wide range of fused thiophenes, including those fused with lactams, lactones, or cyclic ethers, was developed from a rhodium-catalyzed intramolecular transannulation reaction of alkynyl thiadiazoles. This transannulation reaction provides an efficient platform for the construction of a variety of 5,n-fused thiophenes from readily available starting materials together with the release of molecular
从炔基噻二唑的铑催化的分子内跨环化反应中开发出了一种合成广泛范围的稠合噻吩的方法,包括与内酰胺,内酯或环状醚稠合的噻吩。这种转环反应提供了一个有效的平台,用于从容易获得的起始原料中构建各种5种正熔噻吩,同时释放出分子氮。
