Description

Triethylene glycol di(p-toluenesulfonate) was used in the synthesis of 1-[4-(1,4,7,10-tetraoxa-13-aza-cyclopentadec-13-yl)-phenyl] ethanone.

Application

Triethylene glycol bis(p-toluenesulfonate) serves as a robust, bench-stable promoter for glycosylation and nucleophilic substitution reactions. Its tosylate groups enable efficient activation of hydroxyl functionalities under mild conditions, facilitating C–O and C–C bond formation. The reagent exhibits excellent functional group tolerance and simplifies purification due to its low volatility and crystalline nature, making it well-suited for iterative synthetic sequences in carbohydrate chemistry and natural product synthesis.
