Totally Stereoselective Synthesis of 1,3-Disaccharides through Diels-Alder Reactions

A nonclassical, totally stereoselective synthesis of orthogonally protected 1,3-disaccharides is reported. Enantiomerically pure β-keto-δ-lactones, efficiently obtained from glucal and galactal, are transformed into electron-poor heterodienes and chemo-,

A new procedure for the preparation of β-keto-δ-lactones from sugars and their transformation into glycosyl acceptors in disaccharides synthesis

(matrix presented) Glycals are effective starting materials for the synthesis of enantiopure β-ketone-δ-lactones. They are easily transformed, through a two-step, one-pot reaction, into the corresponding α,α′-dioxothiones which in turn can be quantitative
