Mixed signals: The glycophospholipid 1, consisting of two cholinylphospho‐GalNAc units, two 2‐acetamino‐4‐amino‐2,4,6‐trideoxygalactose rings, three glucose residues each with different linkages to other sugar units, and a ribitolphosphate residue, has been synthesized. Target 1 is recognized by the immune system, but not by the TLR‐2 signaling receptor as previously postulated.

The lipoteichoicacid repeating unit of Streptococcus pneumoniae is a complex pseudopentasaccharide (3). It consists of one ribitol-phosphate, one 2-acetamino-4-amino-2,4,6-trideoxy-galactose, one glucose and two galactosamine residues each differently linked, but both carrying one phosphocholine substituent, at position 6. Suitable building blocks (6–10) for efficient and diastereocontrolled ligations
