The review by Takeuchi and Ferusaki is quite encompassing and, in addition to synthesis and reactivity, the physical and spectroscopic properties of isoxazolidines are discussed in detail. Additional spectral studies on the parent and derivatives include H NMR (68MI41600, 77H(7)201, 78IZV850). 

Various reactivities of isoxazolidines have been discussed in detail by Takeuchi and Furusaki (77AHC(21)207). Attention is drawn to the principal reactions below. 

A number of other syntheses were discussed by Takeuchi and Furusaki and the most common involved reaction of hydroxylamine with selected a,/3-unsaturated ketones to give isoxazolidine-3- or -5-ols, which exist in equilibrium with an open-chain counterpart (77AHC(21)207). A similar equilibrium was observed in the reaction of a,/3-unsaturated ketones with N-hydroxyurea. The geometric orientation of the ring substituents was studied as a dynamic process (Scheme 158) (75TL2337).
