Abstract: Disclosed are methods for conversion of ?-hydroxy carbonyl species and preparation of amino alcohol precursor using bifunctional catalysts derived from layer double hydroxides. By the bifunctional catalyst, the abundant basic sites on HTO allow retro-aldol condensation to outpace direct hydrogenation, thus achieving an exceptional selectivity towards a desired product produced through retro-aldol condensation and then hydrogenation. Accordingly, this method exhibits particular utility in the renewable production of N-acetylethanolamine from biomass-derived N-acetyl glucosamine (GlcNAc) without using homogeneous base as a co-catalyst.
