Pyridinium chlorochromate (PCC) supported on silica gel effects the oxidative cyclization of structurally diverse thiophenolic and phenolic Schiff's bases, thereby providing an efficient and convenient method for the synthesis of a library of 2-arylbenzothiazoles and 2-arylbenzoxazoles.
硅胶上负载的氯铬酸吡啶鎓(PCC)可以对结构多样的硫酚和酚Schiff碱进行氧化环化,从而为合成2-芳基苯并噻唑和2-芳基苯并恶唑的库提供了一种高效便捷的方法。
