Convergent synthesis of (1→2)- and (1→4)-C-linked imino disaccharides†
Abstract
A convergent synthesis of (1→2)- and (1→4)-C-linked imino disaccharides was achieved by applying Nozaki–Kishi coupling of a hydroxyproline-derived carbaldehyde with isolevoglucosenone or levoglucosenone derived enol triflates.
