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.

## 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 Trisubstituted 1,4,5,6,‐tetrahydro‐7__H__‐indolones are obtained in a one‐pot synthesis from conjugated nitroolefins and α‐ketoenamines derived from α‐amino esters and cyclohexane‐1,2‐dione. In some cases bicyclo[3.2.1]octan‐8‐one and 1,2‐oxazine __N__‐oxide derivatives are isolated.
