Entwicklung von Carben-katalysierten asymmetrischen intermolekularen Stetter-Reaktionen und direkt gekreuzter intermolekularer Benzoin-Reaktionen
… (64-99%). This method could be enhanced to a nucleophilic acylation of trifluoromethyl ketimines via the employment of various furan-2-carbaldehydes in the presence of a carbene precatalyst. The corresponding alpha-amino-alpha-trifluoromethyl ketones could be obtained in moderate to very good …

Neue Heterazoliumsalze aus Prolin und Pyroglutaminsäure und Anwendungen in Carben-katalysierten asymmetrischen nucleophilen Acylierungen
… active species of these reactions is a nucleophilic carbene. Consequently, enzyme mimetic asymmetric catalytic processes that are mediated by nucleophilic carbenes in vitro as, for instance, the benzoin condensation, the Stetter and other related nucleophilic acylation reactions have …

Carbene catalyzed asymmetric nucleophilic acylations with novel triazolium salts
… we prepared a variety of chiral, nucleophilic carbenes which has benefited from the expected impact of the fused ring, N-based substituent and nature of the side chain steric demand. Finally, after screening different conditions, we were able to obtain the 1,4 diketones in moderate …
