  A Convenient Synthesis of Conformationally Constrained β-Substituted Tryptophans

  摘要：

  A short and general synthesis for the preparation of various conformationally constrained beta-substituted tryptophans has been elaborated starting from indole, aldehydes and Meldrum's acid by using trimolecular condensation and Curtius rearrangement mediated functional group transformations followed by deprotections, as key-steps. The relative configurations of the two diastereomeric series have been determined indirectly by the measurement of (3)J coupling constants in the corresponding tetrahydro-beta-carbolines, and further supported by means of molecular modelizations.
