Cycloaddition of a (−)-menthone-derived nitrone to racemic but-3-en-2-ol led to two spirobicyclic heterocycles, with opposite configurations at the C atom attached to the OH group. This paper describes the __S__ epimer of the 1-hydroxyethyl substituent in imidazoisoxazole C~17~H~30~N~2~O~3~, (I). Th
