Abstract

original image

Unsymmetrisch/asymmetrisch: Neuartige chirale BiSO-P-Liganden erwiesen sich als wirksam in der Palladium-katalysierten asymmetrischen allylischen Alkylierung von Indolen mit den racemischen Titel-Acetaten durch dynamische kinetische asymmetrische Transformation (DYKAT). Die gebildete Wasserstoffbrücke zwischen der Sulfinylgruppe des Liganden und dem Indol-NH spielt eine wichtige Rolle in der Reaktion.
