Synthesis, Characterization, and Coupling Reactions of Six-Membered Cyclic P-Chiral Ammonium Phosphonite–Boranes; Reactive <i>H</i>-Phosphinate Equivalents for the Stereoselective Synthesis of Glycomimetics
phostone-mimetics of disaccharides. On the basis of these studies, successful protocols were established for the synthesis of β-gluco and α- and β-manno-configured phostones of primary alcohols. Deprotection of the dimeric compounds leads to novel families of α- or β-(1→6)-linked glycomimetics.
