ABSTRACT
In the present work, a series of 2-O-substituted derivatives of 1-[[3,5-dichloro-2-hydroxy phenyl] sulfonyl]piperidine [5a-j] were synthesized. These derivatives were geared up by the coupling of 3,5-dichloro-2-hydroxy benzenesulfonyl chloride [1] with piperidine [2] under dynamic pH control in aqueous media to form parent compound 1-[[3,5-dichloro-2-hydroxyphenyl]sulfonyl]piperidine [3], followed by the substitution at oxygen atom with different electrophiles [4a-j] in the presence of sodium hydride [NaH] and dimethyl formamide [DMF] to give a series of Osubstituted derivatives of sulfonamides bearing piperidine nucleus 5a-j. The synthesized O-substituted sulfonamides were spectrally characterized. The bioactivity of all the synthesized compounds were evaluated against lipoxygenase [LOX], acetylcholinesterae [AChE] and butyrylcholinesterase [BChE] enzymes and found to be having talented activity against butyrylcholinesterase enzyme
