A simple chiral diamine catalyst 1h was successfully applied in the asymmetric cyclopropanation of cinnamone derivatives with stabilized sulfur ylides. The desired cyclopropanation adducts were obtained in moderate yields (up to 68%) with good enantioselectivities (67-93% ee) and excellent diastereoselectivities (>95:5) under mild conditions.
