资源简介：
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.
