Enantioselective synthesis of planar-chiral phosphaferrocenes by molybdenum-catalyzed asymmetric interannular ring-closing metathesis.
Enantioselective synthesis of planar-chiral phosphaferrocenes was realized for the first time by molybdenum-catalyzed asymmetric ring-closing metathesis (ARCM) in up to 99% ee, which is the first application of ARCM to induction of chirality in molecules devoid of stereogenic centers.
