Modus operandi: Catalytic access to the title compounds through a new asymmetric α‐arylation protocol is reported (see scheme). These products are formed in good yields and excellent enantioselectivities by using a new and easily synthesized chiral N‐heterocyclic carbene (NHC) ligand. Advanced DFT calculations reveal the properties of the NHC ligand and the mode of operation of the catalyst.
操作方式:报道了通过新的不对称α-芳基化协议对标题化合物的催化访问(参见方案)。通过使用易于合成的新手性N-杂环卡宾(NHC)
配体,可以高收率和出色的对映选择性形成这些产品。先进的DFT计算揭示了NHC
配体的性质和催化剂的运行方式。
