A high regioselectivity has been observed in the palladium catalyzed allylation of “soft” nucleophiles (pentane-2,4-dione and 4-hydroxy-6-methyl-2-pyrone) when both allylic termini have the same steric requirements and different electronic features.
当两个烯丙基末端具有相同的空间要求和不同的电子特征时,在钯催化的“软”亲核试剂(戊烷-2,4-二酮和4-羟基-6-甲基-2-吡喃酮)的烯丙基化反应中观察到很高的区域选择性。
