WebMobilization of glycals both as glycosyl donors and glycosyl acceptors led to the strategy of glycal assembly. Several new glycosylation techniques were developed to provide practical underpinning for this logic of glycal assembly. Glycal-based paradigms have been shown to be nicely adaptable to solid phase supported synthesis. WebGlycals are the cyclic derivatives of sugars possessing a double bond between carbon 1 and carbon 2 of the ring. If the double bond is present in any other position apart from that between carbon atoms 1 and 2, then that cyclic compound cannot be termed as glycal. The first glycol that was synthesized was named as D-glucal.
