Green, Luke published the artcileUV-Induced 1,3,4-Oxadiazole Formation from 5-Substituted Tetrazoles and Carboxylic Acids in Flow, Formula: C8H5F3N4, the publication is Chemistry – A European Journal (2020), 26(65), 14866-14870, database is CAplus and MEDLINE.
A range of 1,3,4-oxadiazoles I (R1 = cylopropanyl, C6H5, 2-MeOC6H4, 4-FC6H4, etc.; R2 = Me, C6H5, 4-MeC6H4, 2-furanyl, etc.) have been synthesized using a UV-B light activated flow approach starting from carboxylic acids and 5-substituted tetrazoles. The application of UV light represents an attractive alternative to the traditional thermolytic approach and has demonstrated comparable efficiency and versatility, with a diverse substrate scope, including the incorporation of highly substituted amino acids.
