Abstract Successive condensation of derivatives of the trisaccharide, biological repeating-unit of the O-antigenicpolysaccharide of Salmonella newington , followed by removal of protecting groups, has given the hexa- and nona-saccharides. The structures of these oligosaccharides were confirmed chemically and by 13 C-n.m.r. spectroscopy.
