✦ Synopsis

The ytterbium triflate catalyzed 1,3-dipolar cycloaddition of diphenylnitrone (I) with the crotylamides (II) is investigated. The diastereoselectivity is found to depend on the nature of the amide auxiliary and the solvent.

## 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.
