Our work included a synthesis of three new imine derivatives-1,3-thiazinan-4-one, 1,3-oxazinan-6-one and 1,3-oxazepin-4,7-dione-which contained an adamantyl fragment. These were produced via the condensation of the Schiff`s base (E)-N-(adamantan-1-yl)-1-(3-aryl)methanimine with 3-mercaptopropanoic acid; 3-chloropropanoic acid; and maleic, citraconic anhydride, respectively. These new imines were prepared via the condensation of adamantan-1-ylamine and 3-nitro-, 3-bromobenzaldehyde in n-BuOH. We obtained a good yield of products. FTIR, 1 H NMR spectroscopy and C.H.N.S analysis were used to diagnostic the products. The molecular structure of (E)-N-(adamantan-1-yl)-1-(3-nitrophenyl)methanimine was confirmed by X-ray crystallography analysis.

“…Oxazepines are heterocyclic unsaturated compounds, incorporating two hetero atoms (oxygen and nitrogen). There are many synthetic strategies for synthesis of oxazepines, using gold-, palladium-and rhodium-based catalysts, [1][2][3] under microwave irradiation, 4 and under catalyst-free conditions 5 as well; all these strategies leading to the formation of 1,3-oxazepines-4,7-diones. Oxazepines were synthesized to be evaluated for their potential activities, e.g.…”

6,7,8,9-Tetrachloro[1,3]oxazepine-1,5-dione derivatives 1b-10b have been synthesized by reacting Schiff bases 1a-10a with tetrachlorophthalic anhydride (TCPA) under (2 + 5 → 7) cycloaddition reaction conditons. All reactions had been monitored using TLC. FT IR and melting points have been used to characterize the Schiff bases; oxazepine compounds 1b-10b were characterized using FT IR, 1 H NMR and their melting points. Biological activity for oxazepine compounds has been evaluated against bacterial types (Staphylococcus aureus, Escherichia coli, Klebsiella spp.) and against a fungus (Geotrichum spp.). Variable activities have been observed against used strains of bacteria and fungi.
