Isoxazolidine is the organic compound with the formula (CH2)3(NH)O. It is the parent of a family of compounds called Isoxazolidines, which are saturated C3NO heterocyclic rings where the nitrogen and oxygen occupy adjacent positions (1 and 2). They are the saturated analogues of Isoxazoles, and they are isomeric with oxazolidines, where the N and O are separated by one carbon.[1]
