  Synthesis of Partially N-Acetylated Chitooligosaccharides and Muropeptides

  摘要：

  Partially N-acetylated chitooligosaccharides and muropeptides are referred to as microbial associated molecular patterns (MAMPs). To shed light on the molecular basis of their recognition by the innate immunity system of living organisms, their production in pure form is necessary. To this end, we present here the first synthetic strategy for the obtainment of a series of partially N-acetylated muropeptides as well as of a chitodisaccharide and a chitotetrasaccharide, all possessing a well-defined N-acetylation pattern.
