The first total syntheses of the antineoplastic glycoside (+)-phyllanthoside (1) and the parent disaccharide (-)-phyllanthose (5) have been achieved. Stereoselective Koenigs-Knorr coupling of two 6-deoxyglucose derivatives, bromide 54 and alcohol 55, generated the uncommon 1′ → 2β glycosidic linkage of (-)-phyllanthose. A stereochemically convergent Mitsunobu reaction of protected disaccharide 87 with aglycon carboxylic acid 80, prepared via asymmetric synthesis, then led to 1 of high enantiomeric purity. The Mitsunobu procedure comprises an efficient general method for stereospecific assembly of β-glycosyl esters.

Several partially benzylated derivatives of 6-deoxy-D-glucose (D-quinovose) were synthesized from appropriate di-O-benzyl-D-glucosides whose primary hydroxyl group is unprotected, via unimolar tosylation and subsequent reduction with LiAlH4.
