Zolimidine is a methylsulfonyl-substituted drug with an imidazo[1,2-α]pyridine core
used for the treatment of peptic ulcer. Herein, we report the synthesis of unprecedented
N-acetylsulfilimine and -sulfoximine analogues under mild conditions. Deprotection
of the N-acetylsulfoximine allows the preparation of the corresponding NH-sulfoximine.
