N,N‐Dialkylhydrazones as Versatile Umpolung Reagents in Enantioselective Anion‐Binding Catalysis

An enantioselective anion‐binding organocatalytic approach with versatile N,N‐dialkylhydrazones (DAHs) as polarity‐reversed (umpolung) nucleophiles is presented. For the application of this concept, a highly ordered hydrogen‐bond (HB) network between a carefully selected CF(3)‐substituted triazole‐b...
