Abstract

1,3-Dipolar cycloaddition of nitrile oxides and nitrones with 2-methylene-1,3-dithiane gave 5-substituted isoxazolines and isoxazolidines in good yield. By treatment with mercuric chloride or NBS isoxazolidine (12) was converted to corresponding lactone (13) which was a precursor of β-amino acid.
