A general and efficient method for the palladium-catalyzed carbonylative coupling of aryl iodides to benzyl acetylenes has been developed. Various furanones have been prepared in excellent yields from their corresponding benzyl acetylenes at room temperat

Two series of pyridazinone derivatives (19-34) were synthesized and evaluated for antitubercular activities against Mycobacterium tuberculosis H37Rv strain. The results illustrated that among the synthesized compounds, compound 25, 5-(4-hydroxy-3-methoxybenzyl)-3-(4-chloro-phenyl)-1,6-dihydro-6-pyridazinone emerged as a lead compound with good antitubercular activity. Four more compounds, (21, 22, 29 & 33) were significant in their antitubercular action.

A series of pyridazinone derivatives (1934) were synthesized with an aim to synthesize safer anti-inflammatory agents. The compounds were evaluated for their anti-inflammatory, analgesic, ulcerogenic and lipid peroxidation (LPO) actions. The percentage inhibition in edema at different time intervals indicated that compounds 20, 26, 28 and 34 exhibited good anti-inflammatory potential, comparable with that of ibuprofen (85.77%) within a range of 67.4877.23%. The results illustrate that 5-(4-fluoro-benzyl)-3-(4-chloro-phenyl) -1,6-dihydro-6-pyridazinone (26) and 5-(4-chloro-benzyl)-3-(4-chloro-phenyl)-1, 6-dihydro-6-pyridazinone (20) showed best anti-inflammatory activity. Furthermore, activity is more in case of chloro substitution as compared with methyl-substitution. The compounds synthesized were also evaluated for their ulcerogenic and LPO action and showed superior gastrointestinal safety profile along with reduction in LPO as compared with that of the ibuprofen.

Making use of CO: An improved efficient synthesis of 5-aryl-3- alkylidenefuran-2-ones has been developed (see scheme). Starting from readily available (hetero)aryl bromides or aryl triflates and alkynes, furanones were produced in good yields through a do

, p. 292 - 297 (2008/09/20)
The microwave-mediated reaction of 4-aryl-4-oxobutanoic acids with benzylamines furnished 1-arylmethyl-3-[(E)-1-arylmethylidene]-5-phenyl-2,3- dihydro-1H-pyrrolones. This result is in contract to the earlier report on this reaction conducted under neat conditions. Structures for the products were assigned on the basis of spectral data and confirmed by independent synthesis.
Stereospecific Palladium(II)-Catalyzed Cyclocarbonylation of 3-Aryl-1-propynes and Iodoarenes of Acid Chlorides To Form (E)-3-Arylidenebutenolides
Huang, Yujin,Alper, Howard
, p. 4534 - 4536 (2007/10/02)
Iodoarenes react with 3-aryl-1-propynes and carbon monoxide, in the presence of palladium acetate and triphenylphosphine, to form (E)-arylidenebutenolides in 33-88percent isolated yields.The same product is formed by substitution of acid chloride for a io
