A one-pot reaction to synthesize functionalized 2H-azirines through visible-light-mediated ring contraction and olefin metathesis of isoxazoles is described. Hoveyda–Grubbs II catalyst was found to function as a photocatalyst for these transformations, allowing these processes to be carried out in a one-pot manner. This study offers a new entry for the application of Grubbs catalysts as efficient photocatalysts
描述了通过可见光介导的环收缩和异恶唑的烯烃复分解反应合成官能化2 H-叠氮基的一锅反应。发现Hoveyda–Grubbs II催化剂可作为这些转化的光催化剂,使这些过程可以一锅法进行。这项研究为将Grubbs催化剂用作有效的光催化剂提供了一个新的切入点,并且为一锅法进行其他光反应和烯烃复分解提供了可能性。
