Generation of Threonine- and Azathreonine N-Carboxy Anhydrides from α-Hydroxy β-Lactams Promoted by 2,2,6,6-Tetramethylpiperidinyl-1-oxyl (TEMPO) in Combination with Sodium Hypochlorite
摘要:
A versatile one-pot oxidation-Baeyer-Villiger reaction sequence applied to alpha-hydroxy beta-lactams and promoted by 2,2,6,6-tetramethylpiperidinyl-1-oxyl (TEMPO) leads to alpha-amino acid N-carboxy anhydrides. The examples reported constitute the first application of TEMPO in a Baeyer-Villiger reaction and provide a way for peptide coupling from non alpha-amino acid precursors.
