Visible Light-Mediated Organocatalyzed 1,2-Sulfonylation/Acylation Cascade of Allenes for Stereodefined Tetrasubstituted Alkenes

Stereodefined tetrasubstituted alkenes are privileged structural motifs widely found in pharmaceuticals, functional materials, and synthetic intermediates. However, the direct, modular, and stereocontrolled assembly of these skeletons from simple precursors remains...
