An atom-economical method for accessing tetrasubstituted 4,5-biscarbonylimidazoles by reaction between glycine derivatives and 5-alkoxyoxazoles is reported. The method, which involves a copper-catalyzed aerobic oxidative [2 + 3] cyclization/aromatization
Treatment of (triethylsilyl)diazoacetates with rhodium(II) octanoate and a range of substituted nitriles generates trisubstituted oxazoles bearing a triethylsilyl group in the 4-position. Fluoride-mediated desilylation yields 3,5-disubstituted oxazoles, w
