The photoaddition of oxygen to organic molecules is a well documented reaction (1,2a) but the title compounds do not appear to have been studied in this connection. Irradiation (3) of a benzene solution of the oxazinone (Ia) (4) in aerated solutions gave a product, m.p. 213-6' (ex-acetone) for which
## Abstract The aza‐Wittig reactions of benzaldehyde‐, acetophenone‐ and benzophenone 1‐[(triphenylphosphor‐anylidene)amino]ethylidenehydrazones (**1**) with 2,3‐furandiones **6** provide a new route to 4__H__,8__H__‐1,2,4‐triazolo[1,5‐__c__][1,3]oxazepin‐4‐ones **14** or 5,6‐dihydro‐7__H__,12__H__
## Abstract Optically active (perfluoroalkyl)‐oxazepin‐7‐ones were synthesized in two steps starting from ethyl perfluorobut‐2‐ynoate by direct addition of optically active amino alcohols __via__ intermolecular __Michael__ addition and lactone formation.
