Abstract :
Carbohydrate derivatives with a spiro-isoxazoline moiety as present in psammaplysins and ceratinamides (metabolites isolated from marine sponges) were prepared in good yields and excellent regio- and diastereoselectivity by a route involving Wittig olefination and 1,3-dipolar cycloaddition as key steps.
