Carbene catalyzed asymmetric nucleophilic acylations with novel triazolium salts
… the benzoin condensation and intramolecular Stetter reaction. The optimal conditions were identified and allowed for an expansion of the reaction scope with 8-95% yield and enantiomeric excesses of 21-95% in the benzoin condensation. Furthermore, these carbene precatalysts have been applied …

Entwicklung von Carben-katalysierten asymmetrischen intermolekularen Stetter-Reaktionen und direkt gekreuzter intermolekularer Benzoin-Reaktionen
… employed in the asymmetric intermolecular Stetter reaction. The resulting 1,4-diketones were obtained in moderate to excellent yields (49-98%) and good enantioselectivities (56-78% ee). For several Stetter products the enantiomeric excess could be enhanced by a single recrystallization up …
