Abstract
Treatment of bis(o-nitrophenyl)disulfides 1 with SmI2 led to simultaneous reduction of nitro groups and reductive cleavage of S–S bonds as well as the formation of the active intermediates 2. The intermediates 2 reacted smoothly with aldehydes or ketones, acid chlorides or anhydrides, α-bromoketones, and α,β-unsaturated ketones at room temperature to afford the desired benzothiazolines 3, benzothiazoles 4, 2H-1,4-benzothiazines 5, and 2,3-dihydro-1,5-benzothiazepines 6, respectively, in moderate to high yields under mild and neutral conditions. © 2001 John Wiley & Sons, Inc.
