摘要

Abstract: A 1, 3-dipolar azide–alkyne cycloaddition has been used to prepare a magnetic nanoparticle immobilized MacMillan catalyst that catalyzes the enantioselective 1, 3-dipolar cycloaddition between nitrones and α, β-unsaturated aldehydes. The catalyst can be recovered and recycled for five consecutive runs without any significant loss in yields and diastereo-and enantioselectivities of the isoxazolidines. Keywords: asymmetric catalysis; ...
