Die Guerbet‐Reaktion wurde vor mehr als 100 Jahren entdeckt. In Kombination mit Noyoris Katalysator wurde nun die erste asymmetrische Variante der Guerbet‐Reaktion erreicht. Die Reaktion ermöglicht die enantioselektive Synthese von chiralen Alkoholen, wieC. Wang und Mitarbeiter in ihrem Forschungsartikel auf S. 11505 beschreiben.
The first example of an asymmetric Guerbet reaction has been developed. Using commercially available, classic Noyori RuII‐diamine‐diphosphine catalysts, well‐known in asymmetric hydrogenation, racemic secondary alcohols are shown to couple with primary alcohols in the presence of a base, affording new chiral alcohols with enantiomeric ratios of up to 99:1. Requiring no reducing agents, the protocol...
