A practical synthetic method for 2,2'‐disubstituted fluorinated binaphthyl derivatives was achieved using magnesium bis(2,2,6,6‐tetramethylpiperamide) [Mg(TMP)2], prepared from LiTMP (2 equiv) and MgBr2 (1 equiv), which allows for access to a variety of fluorinated binaphthyl compounds. The utility of the fluorinated binaphthyl backbone was evaluated in F10BINOL derived chiral mono‐phosphoric acid
使用达到2,2'-二取代的联萘氟化衍生物的实用合成方法镁双(2,2,6,6- tetramethylpiperamide)的Mg(TMP)2 ],从LiTMP(2当量)和MgBr制备2(1当量),可以接触到各种氟化联萘化合物。在F 10 BINOL衍生的手性单膦酸(R)-19中作为手性布朗斯台德酸催化剂评估了氟化联萘主链的效用。催化剂(R)-19在催化对映选择性亚氨基烯反应中表现出色,证明了氟化联萘骨架的潜力。手性27:464–475,2015年。 ©2015 Wiley Periodicals,Inc.
