  Synthesis of d-camphor based γ-amino acid (1S,3R)-3-amino-2,2,3-trimethylcyclopentane carboxylic acid

  摘要：

  Synthesis of a gamma-amino acid derived from (1R,3S)-camphoric acid is described. D-(+)-Camphoric anhydride, prepared from D-(+)-camphoric acid by treatment with methanesulfonyl chloride and triethylamine, was reacted with benzyl alcohol and catalytic DMAP, and subsequently reacted in a Curtius rearrangement to afford the corresponding carbamate derivative. This derivative was converted to the desired gamma-amino acid through hydrogenolysis. (C) 2010 Elsevier Ltd. All rights reserved.
