摘要:
Chiral (salen)manganese(III) complexes (3 and 4) were prepared and used for the enantioselective epoxidation of unfunctionalized olefins. The highest enantioselectivity of 48% ee for the catalytic epoxidation of (E)-stilbene was realized by using 3 as a catalyst though much lower enantioselectivity (7% ee) was obtained for that of (E)-l-phenyl-l-propene. In the epoxidation of (Z)-olefins, enantioselectivities were in the range of 68 approximately 72% ee by using 3 as a catalyst and 60% ee by using 4.
