The cycloaddition reactions of in situ generated silyl nitronates 3 to chiral enone la or enoate l b proceed with high stereoselectivity to give enantiomericaUy pure N-silyloxyisoxazolidines 4, which can easily be transformed into A2-isuxazolines 5. Based on an X-ray analysis the major diastereomer
