The first catalytic route toward the title compounds by asymmetric ring‐closingmetathesis is described. A remarkable reversal of enantioselectivity is observed when the achiral imido ligand of the chiral molybdenum‐catalyst is changed (see scheme), thus highlighting the importance of the achiral and the chiral ligands in catalyst design.
