  2,3-Pyrrolidinedicarboxylates as Neurotransmitter Conformer Mimics: Enantioselective Synthesis via Chelation-Controlled Enolate Alkylation

  摘要：

  Conformationally restricted analogs of naturally-occurring amino acids can serve in a variety of ways as protein structure/function probes. A diastereo- and enantioselective synthesis of the four stereoisomers of 2,3-pyrrolidinedicarboxylic acid (an analog of aspartic acid) are described in this paper. The key step is a Rapoport-type aspartate alkylation that can be controlled to give good yields of either diastereomer as a function of enolate geometry. A novel type of chelation control is proposed to account for these results.
