Abstract
Recent explorations of the structure space of Cr( salen) complexes have led to the rational design of improved catalysts for the asymmetric epoxidation of alkenes. The synthesis of these catalysts is presented and their substrate scope detailed. Catalyst 3a, in combination with triphenylphosphine oxide, gives the highest enantiomeric excesses achieved to date in both stoichiometric and catalytic epoxidation with Cr( salen) complexes.
