Chiral Ti salalen complexes catalyze the asymmetric epoxidation of terminal non‐conjugated olefins with hydrogen peroxide. Modular ligands based on cis ‐1,2‐diamino‐cyclohexane ( cis ‐DACH) were developed, giving high yields and enantiomeric excesses ( ee , up to 96 %) at catalyst loadings as low as 0.1–0.5 mol %, and even under solvent‐free conditions.
