An asymmetric allylic substitution of simple allylic ethers with arylboronic acids in the presence of a rhodium(I)/(R)-DTBM-SEGPHOS catalyst has been developed. The reactions proceeded smoothly at room temperature to give the corresponding branch products with excellent regioselectivities and good to excellent enantioselectivities.
已经开发了在铑(I)/(R)-DTBM-SEGPHOS催化剂存在下用芳基硼酸对简单烯丙基醚的不对称烯丙基取代。反应在室温下平稳进行,得到相应的支链产物,具有优良的区域选择性和良好的至优良的对映选择性。
