A new family of building blocks for combinational synthesis, peptidodisaccharides, is provided containing the peptide linkage. Synthesis is more facile than with the oxygen-linked carbohydrates; the resulting compounds are expected to be more stable to enzymatic and chemical hydrolysis and to be amenable to automated synthesis.

Hartman,James K. Coward |发布日期:2002.8.1 摘要:Catalysis Via Stabilization Of Positive Charges On Or Near The C-1, C-4, C-5, Or C-6 Positions. Substrate Analogues Differing Only In The Substitution Of A Fluorine For The Axial C-5 Hydrogen Would Possess Reduced Electron Density At These Positions And Could Be Useful Mechanistic Probes Of These Enzymes. Introduction Of This 5-Fluoro Substituent After Radical Halogenation Was Problematic Because Of The Incompatibility
