In one aspect, the disclosure relates to a facile strategy to introduce electron-deficient aryl sulfate diesters to silylated hydroxyl groups of carbohydrates and amino acids, among other substrates, wherein selective hydrolysis and the removal of an electron-deficient aromatic group allows for the efficient generation of sulfated carbohydrates, peptides, and other compounds. The incorporation of electron-deficient aryl sulfate diesters in the early stage of the synthesis of glycans, peptides, and the like, disclosed herein avoids time-consuming protecting group manipulations, simplifies the purification of sulfated products, and improves the overall yield and efficiency. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
在某一方面,本公开涉及一种简便策略,用于向糖类、氨基酸及其他底物的硅化羟基引入电子缺乏的芳基硫酸二酯。通过选择性水解以及去除电子缺乏的芳香基团,可以高效生成硫酸化的糖类、肽类及其他化合物。在糖类、肽类等化合物的合成早期阶段引入电子缺乏的芳基硫酸二酯,如本公开所述,可以避免耗时的保护基操作,简化硫酸化产物的纯化过程,提高整体产率和效率。本摘要旨在作为特定领域中的检索工具,并不旨在限制本公开的内容。
