Glycals: preparation and application in organic synthesis

Abstract

Glycals have been received considerable attention for their synthetic utility in carbohydrate chemistry. In general, there are two types of glycals, endo- and exo-glycals, depending on the double-bond position within the sugar ring. Their synthetic utilities have been envisaged by scientific reports. In the present review, synthetic methodology and application of glycal derivatives are described in the field of carbohydrate chemistry and natural products.
