Description

Diethylene glycol di(p-toluenesulfonate) was used in the synthesis of bis(dibenzosulfoxo)-27,30,35,38-tetramethyl-24-crown-6, bis(dibenzosulfoxo)-21,24,29,32-tetramethyl-18-crown-4, dibenzosulfoxo-15,18-dimethyl-12-crown-3 and dibenzosulfoxo-12,15-dimethyl-9-crown-2 macrocycles.

Application

Diethylene glycol bis(p-toluenesulfonate) serves as a reliable, bench-stable diol equivalent in organic synthesis, enabling efficient etherification and protection reactions. Its excellent functional group tolerance and compatibility with standard coupling protocols make it a practical choice for constructing complex scaffolds, including heterocyclic systems and glycosidic linkages.
