  Synthesis of (3S,5S)-3,5-diaminopiperidin-2-one as a conformationally restricted surrogate of Dab-Gly dipeptide

  摘要：

  An efficient and stereospecific synthesis of chiral 3,5-diaminopiperidin-2-one as a novel conformationally restricted surrogate of 2,4-diaminobutanoyl (Dab)-Gly dipeptide has been achieved. The key steps include (i) ruthenium tetroxide (RuO4) oxidation of N-Boc-2-azidometliylpyrrolidines with a catalytic amount of RuO2.xH(2)O in a two-phase system of aq NaIO4/AcOEt and (ii) intramolecular transamidation of the resulting 2-azidomethylpyrrolidin-2-ones with 10% Pd-C in MeOH/H2O (12/1, v/v) under an H-2 atmosphere (3 atm). This methodology represents a powerful tool for the synthesis of Dab-Gly dipeptide surrogate. (C) 2005 Elsevier Ltd. All rights reserved.
