functionalization reactions of acetylenic alcohols with 3-diazooxindoles were first described. Various substituted acetylenic alcohols were well tolerated and the O–H functionalization products were delivered in moderate to high yields. More importantly, these ether products could be easily transformed into spirooxindole-fused oxacycles. A preliminary study of the mechanism revealed that this reaction probably
首次描述了可见光介导的炔醇与 3-二氮杂吲哚的 O-H 官能化反应。各种取代的炔醇具有良好的耐受性,并且 O-H 官能化产物以中等到高产率交付。更重要的是,这些醚产物可以很容易地转化为螺吲哚稠合的氧杂环化合物。对该机理的初步研究表明,该反应可能是通过卡宾转移而不是质子转移途径进行的。
