  Stereospecific synthesis of α-deuteriated α-amino acids: regiospecific deuteriation of chiral 3-isopropyl-2,5-dimethoxy-3,6-dihydropyrazines

  摘要：

  Base-catalysed deuteriation of (3R)- or (3S)-3-isopropyl-2.5-dimethoxy-3,6-dihydropyrazines in refluxing (CH3OH)-H-2-(H2O)-H-2 gives the [6-H-2(2)]-isotopomer in excellent yields without disturbing the stereogenic centre at C-3. These compounds provide convenient and efficient access to a range of (R)- and (S)-alpha-deuteriated alpha-amino acids, including serine, aspartic acid, allylglycine and phenylalanine, via alkylation of the butyllithium generated C-6 anion.

  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.
