Asymmetrische Katalyse Die enantiodivergente kinetische Racematspaltung von 1,1′‐Biaryl‐2,2′‐diolen und Aminoalkoholen durch Dipeptid‐Phosphoniumsalz‐Katalyse wird von Tianli Wang et al. im Forschungsartikel auf S. 15048 berichtet.
A highly enantiodivergent organocatalytic method is disclosed for the synthesis of atropisomeric biaryls via kinetic resolution inspired by a dipeptide‐phosphonium salt‐catalyzed Atherton–Todd (A‐T) reaction. This flexible approach led to both R‐ and S‐enantiomers by fine‐tuning of bifunctional phosphonium with excellent selectivity factors (s) of up to 1057 and 525, respectively. The potential of...
