DOIAbstract
The key step in a new synthesis of 2-acetamido-2,3-dideoxy-(14)-thiodisaccharides was the conjugate addition of a 1-thiogalactose derivative to E and Z acetyl oximes derived from sugar enones. This reaction was shown to be completely diastereoselective for both the formation of the thioglycosidic linkage and the configuration of acetyl oxime. The thiodisaccharides have been designed as inhibitors of the β-galactosidase from E. coli, and they have been shown to successfully meet such requirements.Fil: Dada, Lucas.
