ammonium salt‐catalyzed synthesis of chiral 3,3‐disubstituted isoindolinones bearing a heteroatom functionality in the 3‐position. A broad variety of differently substituted CF3S‐ and RS‐derivatives were obtained with often high enantioselectivities when using Maruoka's bifunctional chiral ammonium salt catalyst. In addition, a first proof‐of‐concept for the racemic synthesis of the analogous F‐containing
我们在此报告了铵盐催化合成在3位带有杂原子官能团的手性3,3-二取代异吲哚啉酮。使用 Maruoka 的双功能手性铵盐催化剂时,可以获得多种不同取代的 CF 3 S 和 RS 衍生物,且通常具有较高的对映选择性。此外,还获得了类似含 F 产品外消旋合成的第一个概念验证,从而获得了相当稳定的 α-F-α-氨基酸衍生物的罕见例子之一。
