Abstract
- A synthetic route has been developed for constructing the d-saccharosamine-l-rhamnose-d-fucose (Sac-Rha-Fuc) trisaccharide fragment present in the antibacterial natural product saccharomicin B. The Sac monosaccharide was synthesized through a modified nine step procedure starting from d-rhamnal in 23% overall yield. 1- O-TBS Sac donors were used to construct the β-linked Sac-Rha disaccharide. This disaccharide was coupled to a Fuc acceptor under BSP/Tf <subscript>2</subscript> O conditions to afford a trisaccharide properly functionalized for elaboration to saccharomicin B.
