Adducts of peptides and arylboronic acids are attractive tools for the selective recognition of carbohydrates. These structures resemble at least some of the properties of natural carbohydrate binders and have therefore been termed lectin mimetics or boronolectins. In this report, we describe the synthesis of appropriately functionalized benzoboroxoles as modular components for the assembly of boronolectins. These benzoboroxoles have been prepared in a few steps from readily available starting materials. In conclusion, versatile functionalized benzoboroxoles are reported that can be used for the construction of larger conjugates by peptide coupling or copper-mediated cycloadditions (click reactions) with azides.
肽和芳基硼酸的加合物是选择性识别碳水化合物的诱人工具。这些结构至少与天然碳水化合物粘合剂的某些特性相似,因此被称为凝集素模拟物或硼电子蛋白。在本报告中,我们介绍了将适当官能化的苯并硼氧烷合成为组装硼电子蛋白的模块成分的方法。这些苯并硼氧烷是用容易获得的起始材料通过几个步骤制备的。总之,我们报告的多功能官能化苯并硼氧烷可用于通过肽偶联或铜介导的环加成反应(点击反应)与叠氮化物构建更大的共轭物。
