Simple and Efficient Preparation of 2,5-Disubstituted Oxazoles via a Metal-Free-Catalyzed Cascade Cyclization
摘要:
A practical and simple synthesis of 2,5-disubstituted oxazoles was developed via an iodine-catalyzed tandem oxidative cyclization. A wide range of common commercial aromatic aldehydes can be used as reaction substrates, which displayed excellent functional group compatibility in this reaction.
