Oxazolidine is a five-membered ring compound consisting of three carbons, a nitrogen, a hydrogen, and an oxygen. The oxygen and NH are the 1 and 3 positions, respectively. In oxazolidine derivatives, there is always a carbon between the oxygen and the nitrogen (or it would be an isoxazolidine).SID 3881507 -- PubChem Substance Summary. The PubChem Project.

Retrieved on 13 December, 2005.Dr Neil G Carter OXAZOLIDINE DILUENTS: REACTING FOR THE ENVIRONMENT Industrial Copolymers Limited All of the carbons in oxazolidines are reduced (compare to oxazole and oxazoline). Some of their derivatives, the oxazolidinediones, are used as anticonvulsants.

Bisoxazolidines

Bisoxazolidines have two oxazolidine rings, and they are used as reactive diluents in polyurethane paints. The rings hydrolyze in the presence of moisture into amine and hydroxyl groups, which can then bind with diisocyanates to form the coating. Emission control chembytes e-zine 2001.

Isoxazolidines

In an isoxazolidine nitrogen and oxygen occupy positions 1 and 2 in the ring:

It is the saturated relative of Isoxazole.
