ChemInform Abstract
The reaction of the optically active title lactone (I) with achiral as well as chiral nitrones results in the regioselective formation of two diastereomeric isoxazolidines. In all cases studied, N-methylnitrones react with higher diastereoselectivity than the corresponding N-phenyl analogues.
