摘要

Isoxazolidines have been synthesized in diastereomeric excess up to 94% via a MgBr2- induced chelation-controlled 1, 3-dipolar cycloaddition reaction with N- hydroxyphenylglycinol as a chiral auxiliary. The diastereomerically pure isoxazolidines were further transformed into cyclic and acyclic β-amino acid derivatives.
