  Diastereodivergent synthesis of 2,5-diketopiperazine derivatives of β-carboline and isoquinoline from l-amino acids

  摘要：

  Mild Pictet-Spengler-type condensation was applied to the synthesis of several tetrahydro-beta-carboline and tetrahydroisoquinoline derivatives. L-Amino acids were promoters of 1,4-chirality transfer with up to 100% de. The stereochemistry of the final diketopiperazines strongly depended on the structure of the L-amino acids used: acyclic amino acids gave predominantly the (R)configuration at the newly created stereogenic centre, whereas L-proline afforded the opposite configuration, as established by Xray crystallography.
