GENERAL DESCRIPTION

Chiral amino alcohols and their N-protected derivatives (Cbz, t-Boc, and Fmoc) are versatile building blocks, auxiliaries, ligand or resolving agent in asymmetric synthesis for biological research and pharmaceutical applications such as antitumor, anesthetic, antipasmodic, hepatotoxic, antiinflammatory or anti-HIV activities. They are used in the synthesis of beta-blockers, HIV protease and ACE inhibitors, chiral auxiliaries and catalytic enantioselective ligands. Their derivatives include the forms of;
  • C-terminal peptibiols
  • Amphiphylic antibacterial peptides
  • Oligocarbamates
  • Analogs of peptides
  • Aziridines, Halogen aminoalkyls
  • Enantiomerical alpha-alkyl mono and diamines
  • Enantiomerical beta-substituted amines
  • Enantiomerical beta-amino acids beta-amino sulfoxides, beta-amino sulfides and beta-amino thiols.
  • The precursors of diverse compounds such as statines, sphingolipides and peptide isosteres.
(R,R)-(-)-2,4-Pentanediol is an effective diol for asymmetric chiral applications such as chiral auxiliaries, building blocks, chiral ligands.
