Extending the catalytic valorization roadmap of platform molecules is likely one of the core duties within the improvement of the biomass conversion discipline. By way of ongoing analysis efforts, the transformation system of biomass-derived platform molecules has been effectively established and is regularly turning into comparatively mature. On this context, it’s of nice sensible curiosity to additional discover next-generation platform molecules and their valorization pathways which have lately emerged. Linear diketones, often derived from biomass and their C6 furan compounds, are one of many novel platform molecules which have been lately spotlighted for the synthesis of high-end chemical compounds resulting from their enormous valorization potential. Herein, we intend to underline the essential platform function that linear diketones, i.e., 2,5-hexanedione (HD) and 1-hydroxy-2,5-hexanedione (HHD), play in extending the biomass valorization roadmap to a broader one. Views are focused on elucidating the heterogeneous tandem conversion system of biomass and its derived C6 furan compounds to HD and HHD. Additionally, we additional display the various valorization routes of HD and HHD to high-end chemical compounds for varied functions. The insights introduced on this paper might contribute to highlighting the intense way forward for linear diketones in establishing a sustainable biomass valorization system.
