SYNTHESIS OF 2,3-DISUBSTITUTED 5,7,7-TRIMETHYL-2,3,6,7-TETRAHYDRO-1,3,4-OXADIAZEPINES AND 6,7-BENZO-2,3-DIHYDRO-1,3,4-OXADIAZEPINES

The corresponding hydrazones were obtained by the reaction of diacetone alcohol and salicylaldehyde with monoalkylhydrazines.It is shown that derivatives of 2,3,6,7-tetrahydro-1,3,4-oxadiazepine and 6,7-benzo-2,3-dihydro-1,3,4-oxadiazepine, respectively, are obtained in the reaction of monoalkylhydrazones of β-hydroxy carbonyl compounds with both the hydroxy group in the alkyl chain and the hydroxy group attached to the aromatic ring with aldehydes.The structures of the products were proved by the set of analytical, IR, and 1H NMR data.
