Studies on the Synthesis of Sesamin-Group Lignans Ⅷ. A Simplified Sythesis of 2-Aryl-4-phenyloxazoles and 2-Alkyl-4-phenyloxazoles

摘要

The reaction of phenacyl benzoate derivatives with acetamide at about 140°in the presence of BF3 catalyst gave 2-aryl-4-phenyloxazoles. This method can be applied to the preparation of 2-alkyl-4-phenyloxazoles as well.
