木质素衍生的化学物质，如香兰素和丁香醛，是具有代表性的生物可再生单体构建模块的聚合物化学。当考虑到香兰素和丁香醛的化学结构时，它们本能地以分子结构中的醛基为特征。由于醛是多组分反应（mcr）中最重要的反应物，我们现在报道了胺、亚磷酸盐和以香兰素和丁香醛为特征的聚合物之间的卡巴尼克场三组分反应（KF-3CR）。以香兰素和丁香醛为特征的聚合物的KF-3CR成功地进行了，几乎完美地消耗了起始醛，基本上提供了聚合物α-氨基膦酸盐。
Lignin-derived chemicals, such as vanillin and syringaldehyde, are representative bio-renewable monomer building blocks for polymer chemistry. When considering the chemical structures of vanillin and syringaldehyde, they instinctively feature aldehyde groups in their molecular structures. Since aldehydes are some of the most important reactants in multi-component reactions (MCRs), we now report the Kabachnik-Fields three-component reaction (KF-3CR) between amines, phosphites, and polymers featuring vanillin and syringaldehyde. The successful KF-3CR of the polymers featuring vanillin and syringaldehyde proceeded with a practically perfect consumption of the starting aldehydes, essentially affording polymeric α-amino phosphonates.
