A concise synthesis of novel homochiral aromatic amino acid surrogates comprising a tetrahydroindazole or a benzisoxazole system was developed via the acylation of a cyclic 1,3-diketone by the side-chain carboxyl functionality of either Boc-Asp-OtBu or Boc-Glu-OtBu followed by regioselective condensation with hydrazine, N-benzylhydrazine and hydroxylamine. The tetrahydroindazole nucleus was also constructed by the condensation of Boc-Asp-OtBu with the enamine, 1-pyrrolidino-1-cyclohexene followed by acid-hydrolytic treatment and reaction with hydrazines. Further functional group transformations gave N-alpha-Fmoc-protected derivatives as useful building blocks for solid-phase peptide assembly. (C) 2003 Elsevier Ltd. All rights reserved.
