Atroposelective Arene‐Forming Alkene Metathesis**

Alkene metathesis catalyzed by enantiopure metal alkylidene complexes enables exceptionally versatile strategies to products with configurationally-defined stereocenters. Desymmetrization processes thereby provide reliable stereoselective routes aliphatic structures, while the differentiation of aromatic stereogenic units remained an outstanding challenge. Herein, we describe feasibility alkene catalytically control axes traceless arene formation. Stereodynamic trienes are selectively converted into corresponding binaphthalene atropisomers upon exposure a chiral molybdenum catalyst. Remarkably, arene-forming allows enantioselectivities up 98 : 2 e.r. and excellent yields. As disconnection each bond target is retrosynthetically conceivable, it anticipated that forging arenes means will enable approaches for synthesis broad range molecular topologies precisely defined configuration.
