No full textA practical route to fluoroalkyl- and fluoroarylamines by base-catalyzed [1,3]-proton shift reaction
No full textThe base-catalyzed [1,3]-proton shift reaction is shown to be an efficient general approach to fluoroalkyl and fluoroaryl amines starting from appropriate carbonyl compounds and benzylamine. The base-catalyzed [1,3]-proton shift reaction is shown to be a convenient general method for preparation of primary fluoroalkyl and fluoroaryl amines starting from appropriate carbonyl compounds and benzylamine
Transamination of fluorinated β-keto carboxylic esters. A biomimetic approach to β-polyfluoroalkyl-β-amino acids.
No full textThe base-catalyzed isomerization of N-benzylimines (or enamines) of β-polyfluoroalkyl-β-ketocarboxylic esters cleanly affords the N-benzylidene derivatives of β-polyfluoro-β-aminocarboxylic esters which are hydrolyzed to corresponding amino acids in high overall yields
