The nitrile oxide–isoxazoline route to higher-carbon dialdoses
Abstract
7-Deoxytrideca-and 6-deoxydodeca-dialdose derivatives are prepared by cycloaddition of D-galactose-derived nitrile oxide 2 to ω-unsaturated heptoses and hexoses and reductive hydrolytic cleavage of the resulting 2-isoxazolines.
