Oxidation of Aromatic Lithium Thiolates into Sulfinate Salts: An Attractive Entry to Aryl Sulfones Labeled with Carbon-11
摘要:
[Graphics]Aromatic C-11-sulfones were synthesized by S alkylation of lithium arenesulfinates, which are readily available from the corresponding thiols by an oxaziridine-mediated oxidation reaction with [C-11]alkyl iodides in THF/H2O (4: 1) at 150 degrees C. The radiosyntheses, including purification by HPLC, were completed in an average of 35 min from the end of the bombardment with 55-76% overall radiochemical yields (decay corrected). The described procedure extends the range of accessible labeling methods.

Several benzene(or phenylmethane) sulfinate esters were synthesized in 53-98% yields from the corresponding methoxymethyl(MOM) sulfides employing NBS as oxidant.
