2-aminobenzofuran 3-enes via the formal C–S insertion reaction of alkyne-tethered diazo compounds. Metal carbene, as a kind of active synthetic intermediate, plays a very important role in organic synthesis. Through the carbene/alkyne metathesis strategy, a new donor carbene is produced in situ as a key intermediate, which has different reactions from the donor receptor carbene.
在此,我们报告了一种通过炔烃系重氮化合物的正式 C-S 插入反应合成 2-氨基苯并呋喃 3-烯的新方法。金属卡宾作为一种活性合成中间体,在有机合成中起着非常重要的作用。通过卡宾/炔烃复分解策略,原位产生新的供体卡宾作为关键中间体,其与供体受体卡宾具有不同的反应。
