Abstract
Trisubstituted oxazoles I react at −15° with singlet oxygen to give dioxazoles III and iminoanhydrides V which rearrange at room temperature to triamides VI. The intermediate ratio (III/V) is sensitive to the reaction temperature. It is likely that at room temperature triamides VI are essentially formed via imino‐anhydrides V.
