Several new thiazoles ( 3–7 ), thiazolylpyrazole carbonitrile ( 10 , 11 ), and Thiazolidine sulfonamido conjugate derivatives ( 19–26 ) were prepared starting with p-Piperidinesulfonylacetophenones ( 1 , 2 ). The structure of these compounds was elucidated on the bases of elemental analysis, IR, PMR, and massspectra. The antimicrobial activities of some selected compounds are also reported.

4-Aryl-3-cyano-6-(2'-thienyl)-pyridine-2(1 H )-thiones ( 2a-c ) were prepared and reacted with chloroacetonitrile or chloroacetamide to furnish 3-amino-4-aryl-6-(2'-thienyl)-thieno[2,3-b]pyridine-2-carbonitriles ( 4a-c ) and 2-carboxamide analogs 6a-c respectively. The reaction of 4a and 6a-c with a variety of reagents namely, formamide, carbon disulfide, phenyl isothiocyanate, ethylene diamine, sodium

to Curtius rearrangement in boiling xylene to give imidazothienopyridine 20. Reaction of 10 with either formic acid or triethylorthoformate and phenyl isothiocyanate gave the corresponding pyridothienotriazepines 22 and 23, respectively. The interaction of 10 with acetylacetone furnished the pyrazolyl derivative 24. The structures of the synthesized compounds were established from their analytical and

Three series of new cyclic sulfones have been prepared by a one-pot multi-component reaction (MCR) starting from the readily available dihydro-2H-thiopyran-3(4H)-one-1,1-dioxide. The in silico screening of the synthesized compounds revealed their high anti-inflammatory, antiarthritic, antiasthmatic and antiallergic potential coupled with the strong probability levels of cystinyl aminopeptidase inhibition
