The structure deter- minations on these compounds were performed by FT-IR spectroscopy which indicated that the terminal alkyl chain attached to the oxazepine ring was fully extended. Conforrnational analysis in DMSO at ambient temperature was carried out for the first time via high resolution 1H NMR and 13C NMR spectroscopy.展开更多
