| description | “Oxazepine” refers to any seven-membered ring containing
an oxygen and nitrogen atom. The 1,3-oxazepine is a branch
of many types of the heterocyclic oxazepine [1–7]. The core
structure of 1,3-oxazepane-4,7diones consists of a sevenmemebred
ring along with two carbonyl group. Over the
years, the syntheses of oxazepine derivatives have been
investigated and documented. The result is important of heterocyclic
compounds having significant biological uses [8–
13]. Recently, we prepared a variety of 1,3-oxazepinediones
in order to study the spectroscopic and liquid crystal
properties [14]. In this paper, we present the structural
elucidation by 1D and 2D NMR experiments of 3-alkyl-
2-(3-hydroxyphenyl)-1,3-oxazepane-4,7-diones with general
formula(HOC6H4)CONCnH2n+1CH-CH(CO)2 (where n =
2, 4, 6, 8, 10, 12, 14, 16, and 18). Here, the hydroxyphenyl
and the terminal alkyl chain are attached to the oxazepane
ring. |
