A gold-catalyzed formal 1,3-dipolar [3 + 2] annulation using readily accessible N-acyl sulfilimines and ynamides is reported. This reaction includes the cleavage of a N–S bond and subsequent C–O bond formation. In total, 30 oxazole derivatives bearing diverse functionalities could be prepared in 43–98% yield from the corresponding sulfilimines and ynamides.
据报道,使用易于获得的N-酰基亚硫亚胺和乙酰胺,可以催化金催化的1,3-偶极[3 + 2]环化反应。此反应包括N–S键的断裂和随后的C–O键的形成。总共可以从相应的硫亚胺和乙酰胺制备43-98%收率的30种具有多种功能的恶唑衍生物。
