Silver(I)-Catalyzed Deprenylation of Allylsulfonamide Derivatives

Abstract

The silver(I)-catalyzed deprenylation of sulfonamide bearing prenyl functional groups on the nitrogen atom has been developed. In this reaction, the prenyl moiety was selectively eliminated without allyl or benzyl cleavage on the nitrogen atom. In addition, geranyl was also applicable for this elimination reaction. Furthermore, sulfonamide possessing two prenyl groups underwent a double deprenylation to form the corresponding deprenylated sulfonamide. Thus, a novel reactivity between the silver cation and double bond was observed.

Key words

C–N bond cleavage - silver - catalytic reaction - deprenylation - alkene

• 28 General Procedure for Deprenylation To a solution of substrate (0.10 mmol) in DCE (0.5 mL) was added a solution of AgSbF₆ (0.005 mmol) in DCE (0.5 mL) under an atmosphere of N₂. After stirring for 2 min at 140 °C under microwave irradiation, the solvent was evaporated off. The residue was chromatographed with hexane/EtOAc to afford the deprenylated sulfonamide.
