Synthesis of azide-alkyne fragments for 'click' chemical applications. formation of chiral 1,4-disubstituted-(β-alkyl) γ- 1,2,3-triazole scaffolds from orthogonally protected chiral β-alkyl-trialkylsilyl γ- Pentynyl azides and chiral β-alkyl γ- Pentynyl-alcohols

Abstract

A library of chiral γ-pentynyl alcohols and γ-pentynyl azides was made using the SuperQuat auxiliary. Coupling of the free alkynes with the azides by Huisgen 1,3-dipolar cycloaddition provided chiral oligomeric 1,4-disubstituted-1,2,3-triazoles as possible peptidomimetic compounds. © 2010 CSIRO.
