The depolymerization of the biopolymer lignin can give pure aromatic monomers but selective catalytic approaches remain scarce. Here, an approach was rerouted to deliver an unusual phenolic monomer. This monomer's instability proved challenging, but a degradation study identified strategies to overcome this. Heterocycles and a useful synthetic intermediate were prepared. The range of aromatics available
生物聚合物
木质素的解聚可以得到纯的芳族单体,但是仍然缺乏选择性的催化方法。在这里,改变了一种方法来输送一种不常见的
酚醛单体。这种单体的不稳定性被证明具有挑战性,但是降解研究确定了克服这一问题的策略。制备了杂环和有用的合成中间体。
木质素中来自β-O-4单元的芳香族化合物的范围得到了扩展。
