通过多组分反应获得高度多样化的聚合物结构是非常可取的；然而，高效的梅尔德鲁姆基于酸的多组分反应在聚合物化学中很少被强调。在这里，将梅尔德鲁姆酸、吲哚和醛的三组分反应引入到聚合物合成中。梅尔德鲁姆的酸、双醛和二吲哚的直接多组分聚合可以在温和的条件下进行，从而得到结构明确、相对分子质量高的复杂的梅尔德鲁姆含酸聚合物。此外，几乎定量的后聚合改性也可以通过这种梅尔德鲁姆的酸基多组分反应进行。这些结果表明，梅尔德鲁姆的酸基多组分反应将是一种潜在的制备新型聚合物的工具。
Providing access to highly diverse polymer structures by multicomponent reactions is highly desirable; efficient Meldrum's acid‐based multicomponent reactions, however, have been rarely highlighted in polymer chemistry. Here, the three‐component reaction of Meldrum's acid, indole, and aldehyde is introduced into polymer synthesis. Direct multicomponent polymerization of Meldrum's acid, dialdehyde, and diindole can perform under mild conditions, resulting in complex Meldrum's acid‐containing polymers with well‐defined structures, and high molecular weights. Additionally, nearly quantitative postpolymerization modification can also perform via this Meldrum's acid‐based multicomponent reaction. These results indicate that Meldrum's acid‐based multicomponent reaction will be a potential tool to prepare novel polymers.
