  Conformational effects in reversed-phase liquid chromatographic separation of diastereomers of cyclic dipeptides

  摘要：

  The capacity factors, k', of 11 cyclic dipeptides (X-Y) including diastereomers have been determined on an RP-HPLC column in 30% and 50% methanol and 10%, 30%, and 50% acetonitrile solutions. These factors are roughly correlated with hydrophobic parameters, such as octanol-water partition coefficients estimated and k' values for alcohols. For a pair of diastereomers of cyclic (L-X-L-Phe) and (L-X-D-Phe) derivatives k'LL is larger than k'LD, and for cyclic (D-Ala-L-Trp) and (L-Ala-L-Trp) k'LL is smaller than k'DL, particularly in highly aqueous solutions. These elution orders can be well predicted by the holistic molecular surface area approach which takes into account the folded structures of cyclic dipeptides. The present results will be useful for prediction of the log k' values of larger peptides and the hydrophobicity and related properties of peptides.

  Design, Synthesis, and Application of Enantioselective Coupling Reagent with a Traceless Chiral Auxiliary

  摘要：

  Stable chiral N-triazinylbrucinium tetrafluoroborate enantioselectively activates racemic carboxylic acids yielding enantiomerically enriched amides, esters, and dipeptides with er from 8:92 to 0.5:99.5. Due to the departure of a chiral auxiliary after the activation of the carboxylic function, all of the subsequent stages of the coupling reaction proceed without any perturbation caused by a chirality discriminator (traceless). Therefore, the advantageous coupling conditions, configuration, and enantiomeric purity of the final product are entirely predictable from the model experiment.
