Abstract

„Nach eigenem Ermessen“ liefert eine latente HF‐Quelle das aktive katalytische Wasserstofffluorid‐Salz 1‐HF für die enantioselektive organokatalytische Protonierung von Silylenolaten mithilfe leicht verfügbarer Cinchona‐Alkaloid‐Katalysatoren (1). Dieser metallfreie Ansatz führt zum hoch enantioselektiven Protonentransfer (bis 92 % ee) unter milden, neutralen Bedingungen (siehe Schema, TMS=Trimethylsilyl).
