Sultones were subject to ring opening by nucleophilic attack with [(18)F]fluoride to afford easily purified (18)F-labelled hydrophilic sulfonated products in high yields. A two-step sequence including radiofluorination and coupling to lysine was then developed from a bis-sultone precursor as a

Acetolysis of methyl 5,6-di-O-acetyl-2,3-O-isopropylidene-β-L-gulofuranoside has yielded a sultone, 4-(1,2,5,6-tetra-O-acetyl-β-L-gulofuranos-3-yl)-6-methyl-1,2-oxathiin 2,2-dioxide (2) whose structure was determined by X-ray diffraction. (1)H and (13)C NMR spectral properties of 2 are presented together with a rationale for its formation. Preparation and properties of the
Rhodium-catalyzed reactions of sulfonate ester derivatives are biased strongly toward 1,6-insertion and thus offer a general method for assembling delta-sultones. Two protocols for staging this cyclization reaction are described, which capitalize on the unique ability of either diazo or iodonium
A novel homobifunctional cross-linker based on a bis-sultone benzenic scaffold was synthesised. The potential utility of this bioconjugation reagent was demonstrated through the preparation of an original prosthetic group suitable for the [(18)F]-labelling of peptides. The labelling strategy is based
