The first catalyticasymmetric1,3-dipolarcycloaddition of electron-deficient carbon–carbon triple bonds with azomethineylides has been established. This reaction provides an unprecedented approach to access novel 2,5-dihydropyrrole derivatives with potential bioactivities in perfect enantioselectivities of up to >99% ee.
