The synthesis of two complex acetyl azides 6 and 10 having an heteroaryl residue bound to the acetyl group through the ring nitrogen, and their further transformations into the corresponding carbamates 7a-b and 11a-b and isocyanates 16 and 14 are described.Hydrolysis of these products results in the elimination of the substituted methyl group from the heterocyclic residue and formation of 1-unsubstituted heterocycles.A similar transformation was also observed under mass measurement conditions.

3-Benzoylamino-7,7-dimethyl-5-oxo-5,6,7,8-tetrahydrocoumarin (1a) was used as a synthon in the preparation of the first derivatives of the pyranoazepine system 2 and in two approaches to pyridoazepines 4.
