Nitrodisulfides were reduced by SmI₂/HMPA in anhydrous THF at room temperature to produce active intermediates (samarium thiolates and amides), which were "living" double-anions and reacted smoothly with aldehydes or ketones to afford benzothiazolines in good yields under mild and neutral conditions.
