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.
