Rearrangement of Nα-Protected l-Asparagines with Iodosobenzene Diacetate. A Practical Route to β-Amino-l-alanine Derivatives
摘要:
A general synthetic method for the Hofmann rearrangement of protected asparagines has been developed. Reaction of asparagine derivatives with iodosobenzene diacetate (PIDA) in mixed solvents produces beta-amino-L-alanines in good yield. Advantages over the commonly used reagent bis(trifluoroacetoxy)iodobenzene have been discussed.
