Three-component coupling reactions of aldehydes, hydroxylamines, and alkenes proceeded smoothly in the presence of a catalytic amount of a lanthanide triflate, to afford isoxazolidine derivatives in high yields with high diastereoselectivities. The asymmetric 1,3-dipolar cycloaddition using a chiral lanthanide catalyst is also described.
