An efficient zinc‐catalyzed oxidative cyclization of readily available indoly ynamides has been developed, enabling rapid and practical access to a diverse array of valuable medium‐sized lactams in mostly good to excellent yields with wide substrate scope. In addition, such an asymmetric synthesis has also been explored by employing the chiral substrate.
已开发出一种有效的锌催化氧化环化反应,该反应可轻易获得的二氢吲哚酰胺,可快速实用地获得各种有价值的中型内酰胺,且收率范围从大到优,而且具有广泛的底物范围。另外,还已经通过采用手性底物探索了这种不对称合成。
