bearing a 3,3′‐halogen‐substituted chiral 1,1′‐bi‐2‐naphthol (BINOL) unit manifest a new structural motif for chiral‐anion generators. Their unique properties are revealed through highly enantioselective desilylative kinetic resolution of a variety of silyl‐protected racemic alcohols with KF (see scheme).
掌握氟化物:带有3,3'-卤素取代的手性1,1'-bi-2-萘酚(BINOL)单元的手性羟基封端的聚醚为手性阴离子发生器显示了新的结构图案。通过KF对多种甲硅烷基保护的外消旋醇进行高度对映选择性的脱甲硅烷基动力学拆分,揭示了它们的独特性能(参见方案)。
