efficient sulfinate‐catalyzed intermolecular addition reaction of α‐substituted allenyl sulfones and allenoates with Michaelacceptors is highlighted. The sequence proceeds under mild conditions to provide a scalable and efficient access to versatile functionalized alkynes, displaying a quaternary stereocentre at the propargylic position. This work enriches the diversity of Lewis base organocatalysts
