Abstract
A series of highly substituted isoxazolidines with substituents at various ring positions has been synthesised and their 1H NMR spectra recorded over a range of temperatures. The NMR spectra at low temperatures indicate the presence of two invertomers due to slow nitrogen inversion, except in 11-16. The nitrogen inversion barriers are determined using complete line shape analysis, and their dependence on steric factors and H-bonding is discussed.
