A facile and efficient one-pot synthesis of β-hydroxy-γ-lactams from α,α-dialkyl β-oxo amides and trimethylsulfoxonium iodide in the presence of sodium hydride via a tandem CoreyâChaykovsky reaction and an intramolecular lactamization process is developed.
开发了一种简便高效的一锅法合成β-羟基-γ-内酰胺的方法,该方法利用α,α-二烷基β-氧代酰胺与三甲基亚磺酰碘在氢化钠存在下通过串联的Corey-Chaykovsky反应和分子内内酰胺化过程合成。
