Synthesis of galactosaminyl d-chiro-inositols Original Research Article

All six isomeric d-galactosaminopyranosyl-d-chiro-inositols have been prepared by glycosylation of appropriate penta-O-benzyl-d-chiro-inositols. The three requisite protected d-chiro-inositols were prepared by SmI2-promoted pinacol coupling of dialdehydes derived ultimately from l-arabinose.
