A newly prepared trinuclear Zn3-(R,S,S)-aminoiminobinaphthoxide complex (triZn-II) catalyzed the first general intermolecular asymmetric iodoetherification of unfunctionalized alkenes. Using triZn-II, the iodoetherification reaction of unfunctionalized alkenes with o-nitrophenols proceeded smoothly to give the products with up to 92.5:7.5 er, and diene substrates were converted to the products with
新制备的三核 Zn 3 -( R , S , S )-氨基亚氨基萘酚盐络合物 ( triZn-II ) 催化了非官能化烯烃的第一次一般分子间不对称碘醚化。使用triZn-II,非官能化烯烃与邻硝基苯酚的碘醚化反应顺利进行,得到高达92.5:7.5 er的产物,二烯底物转化为高达99:1 er的产物,形成内消旋体-异构体(dl / meso = 78/22)。手性碘醚为手性吗啉的合成提供了新的平台。
