The structure of the capsularpolysaccharide (CPS) of serotype Ia groupBStreptococcus (GBS) has been characterized for years, but its repeatingunit, which is a challenging pentasaccharide with a branch and a difficult α-sialic acid linkage, has not been synthesized yet. In this report, an effective synthesis was developed for the serotype Ia GBS CPS repeatingunit, which had a reactive functionality
