An Ir(P,alkene) complex catalyzes the enantioselective allylic etherification of unactivated secondary allylic alcohols. Useful levels of enantioselectivity and yield were achieved with this operationally easy and robust protocol. Initial kinetic studies indicate a significant rate difference for the substrate enantiomers, allowing for a resolution process. cod=1,5‐cyclooctadiene
Ir(P,烯烃)络合物催化未活化的仲烯丙基醇的对映选择性烯丙基醚化。通过这种操作简单,功能强大的方案,可以达到有用的对映选择性和产率水平。最初的动力学研究表明底物对映异构体的速率存在显着差异,从而可以实现拆分过程。鳕鱼= 1,5-环辛二烯
