Significance
Retro-aldol reactions of biomass-derived monosaccharides enable the production of a number of industrially relevant, renewable platform chemicals (e.g., C 2 –C 4 α-hydroxy carboxylic acids, acrylic acid, and esters thereof; and ethylene and propylene glycol). Here, we show a set of retro-aldol catalysts that can perform these reactions at significantly lower temperatures (∼100 °C) than previously reported, and demonstrate that these catalysts enable the key retro-aldol step when used in combination with a 1,2-hydride shift catalyst to create a reaction cascade that converts ketohexoses to lactic acid. The use of moderate temperatures enables numerous desirable features such as lower pressure and significantly less catalyst deactivation.
