Just recently, a pair of β-glycolipids was isolated from the cell membrane of Mycoplasma pneumoniae as a mixture of the two compounds. They are the major immunodeterminants of this pathogenic Mycoplasma and indicate high medicinal potential. They have a β-(1→6)-linked disaccharide structure close to each other; one has β-d-galactopyranoside (β-Gal-type 1) at the non-reducing terminal, and another has β-d-glucopyranoside (β-Glc-type 2). In the present study, the first stereoselective synthesis was conducted for each of the two β-glycolipids 1 and 2. 1H NMR and TLC-immunostaining studies of the synthetic compounds enable us to establish the absolute structures having the β-(1→6)-linked disaccharides at the glycerol sn-3 position.
