Chromatography-free synthesis of 2A,2B-disulfonated β-cyclodextrin for regiospecific di-substitution

Abstract

Cyclodextrins and their derivatives have extensive applications across pharmaceuticals, cosmetics, and the food industry due to their unique hydrophobic cavities. While monosubstituted cyclodextrin derivatives have established synthesis protocols, di-substituted derivatives pose significant challenges, including low yields and complex purification processes. This study presents a novel methodology for synthesizing di-substituted cyclodextrin derivatives, achieving a 33 % yield without relying on chromatographic techniques. This new approach streamlines the synthesis and purification process, making it more practical for large-scale applications and enhancing the utility of cyclodextrin derivatives in various industries.
