p-Toluenesulfonic anhydride (Synonyms: 4-Methylbenzenesulfonic anhydride) is a useful electrophilic reagent for the preparation of various target compounds, such as palladium-catalyzed allylic alkenylation of allylic alcohols with n-butyl acrylate, Regioselective Bromination of Fused Pyridine N-Oxides and SN2-glycosylation for the direct synthesis of β-linked 2-deoxy-sugars.
Palladium-catalyzed allylic alkenylation of allylic alcohols with n-butyl acrylate. [1]
Regioselective Bromination of Fused Heterocyclic N-Oxides. [2]
A reagent-controlled SN2-glycosylation for the direct synthesis of β-linked 2-deoxy-sugars. [3]
