Three‐in‐one: A short synthetic route readily gives access to a new class of chiral (P,N) ligands characterized by three distinct elements of chirality. These ligands are highly enantioselective in the challenging Pd‐catalyzed intramolecular asymmetric α‐arylation of α‐branched aldehydes (see picture).
三合一:合成路线短,可轻松获得以手性的三个不同元素为特征的新型手性(P,N)配体。这些配体在具有挑战性的Pd催化的α-支化醛的分子内不对称α-芳基化反应中具有很高的对映选择性(见图)。
