生物质增值已成为一种有前途和可持续的容纳增值化学品的手段。为了生产这些化学品，近几十年来，对美国能源部（DOE）提名的顶级生物质衍生平台化学品的各种转化方法进行了广泛的研究。然而，以5-羟甲基糠醛为代表的顶级平台化学品研究最为广泛，由于其生产、处理和选择性转化等方面的困难，其应用仍处于开发阶段。在这种情况下，重新审视美国能源部的清单并重新关注其他有效的平台化学品对该研究领域有益。本文介绍了这些平台化学物质，即左旋葡聚糖（+左旋葡糖酮）、烷基糖苷、葡萄糖酸、赤藓糖醇（+1,4-无氢赤藓糖醇）和n -乙酰氨基葡萄糖。利用氢作为还原剂部分或完全去除含氧功能的加氢脱氧是一种很有前途的方法，可以将这些化合物升级为燃料和有用的化学品，而传统的顶级平台化学品很难生产这些化合物。本文总结了实现上述化合物选择性加氢脱氧的各种催化体系，并描述了它们的特征，包括催化性能、活性位点和机理。
Biomass valorization has emerged as a promising and sustainable means of accommodating value-added chemicals. To produce such chemicals, various transformation methods of the top biomass-derived platform chemicals nominated by the U.S. Department of Energy (DOE) have been extensively investigated in recent decades. However, as represented by 5-hydroxymethylfurfural, which is one of the most widely investigated top platform chemicals, their use is still under development due to difficulties in their production, handling, and selective transformation. In this context, revisiting the U.S. DOE's lists and refocusing on other potent platform chemicals are beneficial for this research field. This review introduces such platform chemicals, viz., levoglucosan (+levoglucosenone), alkyl glycosides, glucaric acid, erythritol (+1,4-anhydroerythritol), and N-acetylglucosamine. Hydrodeoxygenation to remove oxygenated functionalities partially or completely using hydrogen as a reductant is a promising means of upgrading these compounds to fuels and useful chemicals, whose production is difficult from conventional top platform chemicals. Herein, a variety of catalytic systems to achieve the selective hydrodeoxygenation of the compounds introduced above are summarized with a description of their features, including catalytic performance, active sites, and mechanism.
