ABSTRACT: We report the novel synthesis of azetidin-2-one derivatives containing aryl sulfonate moiety from the reaction of 2-hydroxy benzaldehyde with p-toluene sulfonyl chloride afforded firstly 2-formylphenyl 4-methylbenzene sulfonate (2). The compound (2) on reaction with p-aminobenzoic acid or 2-aminopyridine gave the corresponding aldimines (3). Furthermore, the aldimines are on reaction with chloroacetyl chloride gives corresponding azetidin-2-ones in good to moderate yield. Among the eight synthesized azetidin-2-ones, five selected compounds have been screened for the an-ti-inflammatory activity, few of them showed good anti-inflammatory activity compared with standard drugs. Anti- microbial activity of all synthesized compounds has been tested and most of the compounds showed good anti-bacterial and anti-fungal activities.
