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 beta-amino acid derivatives.
