An expedient access to the first optically pure ruthenium complexes containing C1-symmetric cyclic (alkyl)(amino)carbene ligands is reported. They demonstrate excellent catalytic performances in asymmetric olefin metathesis with high enantioselectivities (up to 92% ee). Preliminary mechanistic insights provided by density functional theory models highlight the origin of the enantioselectivity.

A new concept in catalytic asymmetric olefin metathesis is introduced: a nonreacting enoate or ynoate group can be used to alter and significantly enhance the enantioselectivity. Catalytic asymmetric ring-opening/cross-metathesis (AROM/CM) processes proce
