The first catalytic asymmetric 1,3-dipolar cycloaddition of electron-deficient carbon–carbon triple bonds with azomethine ylides 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.
