The synthesis of optically enriched atropisomers has so far been limited to molecules containing aryl groups. Now a variant of non-aryl atropisomerism has been identified in vinyl sulfoxonium ylides, and an organocatalytic method has been developed to produce these molecules. This type of axial chirality is characterized by restricted rotation of the central C(sp2)–C(sp2) bond.
