  A series of renewable bisphenols has been synthesized from creosol (2-methoxy-4-methylphenol) through stoichiometric condensation with short chain aldehydes. Creosol can be readily produced from lignin, potentially allowing for the large scale synthesis of bisphenol A replacements from abundant waste biomass. The renewable bisphenols were isolated in good yield and purity without resorting to solvent intense purification methods. Zinc acetate was shown to be selective catalyst for ortho-coupling of formaldehyde but was unreactive with more sterically demanding aldehydes. Dilute HCl and HBr solutions were shown to be effective catalysts for the selective coupling of aldehydes in the position meta to the phenol. Acid solutions could be recycled and used multiple times without decreases in activity or yield.

  一系列可再生的双酚类化合物已经从甲酚（2-甲氧基-4-甲基苯酚）通过与短链醛的化学计量缩合合成。甲酚可以从木质素中轻松生产，潜在地允许从丰富的废弃生物质中大规模合成双酚A替代品。这些可再生的双酚类化合物以良好的产率和纯度分离出来，而无需使用溶剂密集的纯化方法。已经证明乙酸锌是甲醛的邻位偶联的选择性催化剂，但对于更具立体位阻的醛类不具有反应性。稀盐酸和溴化氢溶液被证明是对苯酚的间位选择性偶联的有效催化剂。酸性溶液可以回收并多次使用，而不会降低活性或产率。
