摘要

对羟基肉桂酸及其衍生物是一类具有抗氧化、抗炎、抗肿瘤及抗紫外吸收等生物活性的高附加值化学品，广泛应用于医药、食品、日化及生物基材料等领域。当前，该类化合物主要通过基于传统化石路线的Knoevenagel缩合和Pekin反应，以及基于可再生的草本木质素含酯基片段选择性裁剪反应的途径制备，显然，后者更契合双碳目标需求，是近年来的研究热点。系统综述了高附加值化学品对羟基肉桂酸及其衍生物的价值，并对其制备途径进行了简要的总结，着重阐述了酸、碱、负载型催化剂、离子液体等不同催化体系中木质素定向裁剪制备对羟基肉桂酸及其衍生物的方法，以及对羟基肉桂酸及其衍生物绿色制备的过程强化策略。在此基础上，对对羟基肉桂酸及其衍生物绿色制备潜在的技术瓶颈和可能突破的关键技术方向进行了展望。相关研究可为木质素基高值化学品的绿色制备提供借鉴。

Abstract

Coumaric acid (

CA) and its derivatives have been widely used in the pharmaceutical

food

cosmetic

and bio-based material industries as efficient antioxidant

anti-inflammatory

antitumor

and ultraviolet-absorbing bioactivities. Currently

these compounds are primarily achieved

via

the Knoevenagel condensation or Perkin reaction through a conventional petrochemical route.

Alternatively

selective cleavage of the ester-containing fragments in herbaceous lignin also contribute to the production of

CA and its derivateds. Obviously

the latter is more popular because of the goal of "Carbon peaking and Carbon neutrality". Herein

a comprehensive overview was provided on the significance of

CA and its derivatives as high‑value‑added chemicals. The state-of-the-art approaches for obtaining these chemicals were also summarized. Particularly

the methods for selective cleavage of the ester-containing fraction of lignin using various catalytic systems (

e.g.

acids

bases

supported catalysts

and ionic liquids)

and on the process intensification strategies were extensively emphasized. Furthermore

the potential technical bottlenecks and the key technological directions that have a great potential for leading to breakthroughs in the green synthesis of

CA and its derivates were also proposed. Therefore

the present work would provide a valuable insight for producing lignin-based

biochemicals.
