Synthesis of a cleavable heterobifunctional photolabelling reagent: Ring-labelled 3-[(4-azidophenyl)dithio]propionic acid-^(14)C

Abstract

An efficient synthesis of ring-labelled 3-[(4-azidophenyl)dithio]propionic acid-^(14)C is described. Chlorosulfonation of uniformly ring-labelled acetanilide-^(14)C followed by reductive dimerization of the sulfonyl chloride with HI afforded 4-acetamidophenyl disulfide. Hydrolysis and diazotization then gave 4-azidophenyl disulfide, which was converted to the title compound via the sulfur transfer reagent N-(4-azidophenylthio)phthalimide. The overall yield of 3-[(4-azidophenyl)dithio]propionic acid-^(14)C was 22%. 3-[(4-Azidophenyl)dithio]propionic acid-^(14)C is a cleavable heterobifunctional photolabelling reagent of potential utility in studies of biomembrane structure and intermacromolecular interaction.
