Lignin is one of the most important biomacromolecules in the plant biomass and the largest renewable source of aromatic building blocks in nature. Selectively producing value‐added chemicals from the catalytic transformation of renewable lignin is of strategic significance and meet sustainability targets owing to the excessive consumption of non‐renewable petroleum resource, but remains a long‐term challenge owing to the complexity of lignin structure. This Minireview provides a summary and perspective of the extensive research that provides insight into selectively catalytic transformations of lignin and its derived monomers via directed scissor of chemical linkages (C−O and C−C bonds) with product‐oriented targets. Furthermore, some challenges and opportunities of lignin catalytic transformation are provided based on existing problems in this field for readers to discuss future research directions.

面向产品的木质素化学键的直接裂解。

木质素是植物生物质中最重要的生物大分子之一，也是自然界中最大的芳香族结构单元可再生资源。从可再生木质素的催化转化中选择性地生产增值化学品具有战略意义，并且由于不可再生石油资源的过度消耗而达到了可持续发展的目标，但是由于木质素结构的复杂性仍然是长期的挑战。这份Minireview提供了广泛研究的摘要和观点，该研究提供了对木质素及其衍生单体的选择性催化转化的见解，这些转化是通过化学键（CO和OC键）与产物导向的目标分子的定向剪刀进行的。此外，
