Preparation of novel acyl pyrazoles and triazoles by means of oxidative functionalization reactions
Heterocyclic Communications, 2023 Novel acyl pyrazoles and acyl triazoles have been prepared by means of the oxidative amidation of aldehydes in the presence of the requisite azole. Yields range from modest to good in both cases, and some limitations of the substrate scope have been ...
