Quantitative NMR Approach to Optimize the Formation of Chemical Building Blocks from Abundant Carbohydrates

The future role of biomass-derived chemicals relies on the formation of diverse functional monomers in high yields from carbohydrates. Recently, it has become clear that a series of α-hydroxy acids, esters, and lactones can be formed from carbohydrates in alcohol and water solvents using tin-containing catalysts such as Sn-Beta. These compounds are potential building blocks for polyesters bearing additional olefin and alcohol functionalities. An NMR approach was used to identify, quantify, and optimize the formation of these building blocks in the Sn-Beta-catalyzed transformation of abundant carbohydrates. Record yields of the target molecules can be achieved by obstructing competing reactions through solvent selection. Watching your sugar: A quantitative NMR approach is used to detect, quantify, and optimize the formation of sugar-derived building blocks without depending on reference compounds. Record yields of target molecules are obtained by obstructing competing reactions through solvent selection.
