α-D-lsosaccharino- and α-glucosaccharino-1,4-lactones, readily obtained by alkaline treatment of abundant sugars, represent versatile chiral non-racemic starting materials for the syntheses of molecules containing a tertiary alcohol function. Their usefulness is undoubtedly illustrated by the numerous regio- and stereocontrolled syntheses of biologically relevant molecules such as antibiotics, anticancer agents, pheromones and nucleosides. 1.
