Beta-hydroxy esters are organic compounds that contain both a hydroxyl group (OH) and an ester functional group (RCOOR') within the same molecule. The hydroxyl group is located on the beta-carbon atom relative to the carbonyl group of the ester. This specific arrangement of functional groups gives beta-hydroxy esters unique chemical properties and reactivity.

These compounds can be synthesized through various chemical reactions. A common method is the aldol reaction or its variations, such as the Reformatsky reaction, where an aldehyde or ketone reacts with an alpha-haloester in the presence of a metal like zinc. The resulting intermediate can then be hydrolyzed to yield the beta-hydroxy ester.

Beta-hydroxy esters are versatile intermediates in organic synthesis. They can be readily dehydrated to form alpha,beta-unsaturated esters, which are valuable building blocks for polymerization and other synthetic transformations. Furthermore, the hydroxyl group can be oxidized, or the ester group can be hydrolyzed or reduced, leading to a range of other functionalized molecules. Their presence is also noted in certain natural products and biologically active compounds, highlighting their importance in both synthetic and natural chemistry.
