2,3-O-Isopropylidene-2-C-methyl-D-ribonic-gamma-lactone

Description:

2,3-O-Isopropylidene-2-C-methyl-D-ribonic-gamma-lactone is a chemical compound that belongs to the class of lactones, which are cyclic esters formed from the condensation of hydroxy acids. This specific compound features a five-membered lactone ring and is characterized by the presence of an isopropylidene group and a methyl substituent at the C-2 position of the ribonic structure. The isopropylidene group enhances the stability of the molecule by protecting the hydroxyl groups, making it useful in various synthetic applications. The compound is typically a white to off-white solid and is soluble in polar organic solvents. Its structure allows for potential reactivity in organic synthesis, particularly in carbohydrate chemistry, where it can serve as an intermediate in the synthesis of more complex molecules. Additionally, the presence of stereocenters in its structure contributes to its chirality, which may influence its biological activity and interactions in biochemical pathways.
