A series of substituted thiazole derivatives (6–16) were synthesized to obtain new compounds with potential anti-inflammatory and analgesic activities. At equimolar oral doses, compounds 3-(piperidin-1-yl-methyl)-1, 3, 4-oxadiazol-2-thione (14), 5-amino-4-ethyl ester pyrazole (15), and 5-amino-3-phenylpyrazole derivatives (16) displayed anti-inflammatory and analgesic activities significant to those

and eco-friendly aerobicoxidation of homopropargylic alcohols using Fe(NO3)3·9H2O/TEMPO/NaCl as catalysts at roomtemperature under atmospheric pressure was developed affording corresponding homopropargylic ketones with moderate to good yields. Aryl, heteroaryl as well as alkyl 1,2-allenic ketones were obtained by the isomerization of corresponding terminal homopropargylic ketones through column chromatographic

metal-free redox arylation of alkynes with sulfoxides has been developed to provide unconventional access to diverse γ-arylated 1,3-dicarbonyl compounds in an atom-economical manner. Mechanistic studies suggest that a conjugated allenone intermediate was generated in situ, which solves the problem of reactivity and regioselectivity of unsymmetrical dialkyl-substituted internalalkynes and enables the functionalisation
