A novel Rh(II)-catalyzed transannulation of 1-tosyl-1,2,3-triazoles with silyl or alkyl enol ethers has been developed, which enables the facile synthesis of substituted pyrroles in a regiocontrollable manner. Moreover, the methodology could be extended to access 3-pyrrolin-2-one derivatives with silyl ketene acetals used as the reaction partner.
已经开发了新颖的Rh(II)催化的1-甲苯磺酰基-1,2,3-三唑与甲硅烷基或烷基烯醇醚的环过环化反应,该反应能够以区域可控的方式容易地合成取代的吡咯。此外,该方法可以扩展为使用甲硅烷基乙烯酮缩醛作为反应伙伴来获得3-吡咯啉-2-酮衍生物。
