    Description

    General description

    p-Toluenesulfonic anhydride acts as electrophilic species and activates 2-deoxy-sugar hemiacetals in situ, which reacts stereoselectively with nucleophilic acceptors to afford β-anomers[1].

    Application

    p-Toluenesulfonic anhydride has been employed as reagent in palladium-catalyzed allylic alkenylation of allylic alcohols with n-butyl acrylate[2].

    Packaging

    5, 25 g in glass bottle
