two-step process, which includes the condensation of furanic aldehydes (HMF and 5-acetoxymethylfurfural) with primary amines in methanol on the first step and the reduction of obtained imines with hydrogen in a flow reactor over CuAlOx catalyst derived fromlayereddoublehydroxide on the second step. This process does not require isolation and purification of intermediate imines and can be used to

phase rutile titania supported gold (Au/TiO2-R) catalyst is shown to efficientlycatalyze this CO/H2O-mediated RA undermild and convenient conditions. With this system, a broad spectrum of primary and secondary amines can be used as suitable substrates and the desired reaction can proceed favorably in a highly chemoselective, efficient and atom-economical fashion. In particular, this protocol can also

employed in the reductive amination of HMF under mild conditions. The catalyst shows excellent activity, including a high TON/TOF (h−1) of 604.8/302.4 and ∼94% amine yield, which is maintained over a larger number of reaction cycles (up to 15) when compared to several state-of-the-art materials, such as a commercial Pd/C (3 cycles). It is thought that the origin of the improved catalyst recyclability
