Abstract:
The catalytic reductive amination of furfural derivatives offers a promising route for the synthesis of bio-amines, benefitting sustainable polymer and pharmaceutical industries. Yet achieving a high selectivity of (di)amine remains challenging due to much complex reaction networks and competitive pathways. This focused review summarizes recent advances in strategies for improved biomass valorization through integration of multifunctional active sites for selective reductive amination of furfural derivatives. Three core aspects are summarized and commented, that is, (i) distinctive adsorption mode of substrate, (ii) effective dissociation of hypobaric H2, and (iii) independent activation of NH3. In addition, this focused review proposes the challenges in diamine synthesis and provides the strategies for catalyst design. By getting insights into catalytic mechanism and active site construction, a bright prospect can be foreseen in the near future for more sophisticated valorization of biomass resources.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...
