Discovered by accident: Just because an example of a simple substructure cannot be found in literature does not mean that corresponding compounds are not readily accessible. α‐Azido alcohols like 1‐azidoethanol have now been prepared and isolated.

The photo-sensitized oxygenation of monocyclic 1H-1, 3-diazepines (6) gave several fragment products (7-12). 3-Pyrrolin-2-one derivatives (7 and 8) and ethyl aminoformates (9 and 10) are assumed to originate from the initially formed 4, 7-endoperoxides (13), and vinylaminoformates (11 and 12) from the 4, 5-dioxetanes (14).
