  摘要：

  碳化钨被用作对二甲苯的原子经济和可再生合成的催化剂，具有出色的选择性和4-甲基-3-环己烯-1-羰基醛（4-MCHCA）的产率。该中间体是两种容易获得的生物基丙烯醛和异戊二烯之间的狄尔斯-阿尔德反应的产物。我们的结果表明4-MCHCA通过不涉及外部氢源的分子内氢转移经历了新颖的脱氢芳香化-加氢脱氧级联过程，并且加氢脱氧是通过W 2上C = O键的直接解离而发生的C面。值得注意的是，该方法很容易适用于从生物基合成物中合成各种（多）甲基化的芳烃，因此有可能为有价值的芳族化合物提供不依赖石油的解决方案。

  catalyst in an atom‐economic and renewable synthesis of para‐xylene with excellent selectivity and yield from 4‐methyl‐3‐cyclohexene‐1‐carbonylaldehyde (4‐MCHCA). This intermediate is the product of the Diels–Alder reaction between the two readily available bio‐based building blocks acrolein and isoprene. Our results suggest that 4‐MCHCA undergoes a novel dehydroaromatization–hydrodeoxygenation cascade
