✦ Synopsis

3-Diazo-4-methyl-5-phenylpyrazole readily adds to electron rich olefins to give 1,7-cycloadducts,

The mechanism of the reaction consists of an initial 1,3-dipolar cycloaddition followed by a subsequent rearrangement.

## Abstract 1,3‐Dipolar cycloaddition of nitrones with ethyl vinyl ether or 2,3‐dihydrofuran proceeds smoothly in the presence of a catalytic amount (10 mol%) of ytterbium triflate to afford isoxazolidines and dicyclic isoxazolidine respectively with good yields and high stereoselectivity.
