Significant change in rate acceleration and high yield of these reactions are observed in water compared to organic solvents. All the synthesized compounds have been screened for their antibacterial activity and found to exihibit significant activity. <br/> <br/>Page(s): 1155-1160 Thu, 29 Jul 2010 22:58:59 GMT Synthesis and biological evaluation of some innovative coumarin derivatives containing thiazolidin-4-one ring http://nopr.niscair.res.in/handle/123456789/10089 Title: Synthesis and biological evaluation of some innovative coumarin derivatives containing thiazolidin-4-one ring <br/> <br/>Authors: RamaGanesh, C K; Bodke, Yadav D; Venkatesh, K B <br/> <br/>Abstract: The reaction of ethyl 2-oxo-2<i>H</i>-chromene-3-carboxylate with hydrazine followed by condensation of the resulting hydrazone with different aromatic aldehydes give the corresponding Schiff bases <b style="">5a-e</b>. Reaction of these Schiff bases with mercaptoacetic acid furnishes the target thiazolidinone molecules <b style="">6a-e</b>. The newly synthesized compounds have been screened for antibacterial and analgesic activities. <br/> <br/>Page(s): 1151-1154 Thu, 29 Jul 2010 22:58:59 GMT Synthesis of isoxazolyl quinoline-3-carboxamides and 1,4-benzothiazine-2-carboxamides as potential bioactive compounds http://nopr.niscair.res.in/handle/123456789/10088 Title: Synthesis of isoxazolyl quinoline-3-carboxamides and 1,4-benzothiazine-2-carboxamides as potential bioactive compounds <br/> <br/>Authors: Rajanarendar, E; Murthy, K Rama; Reddy, M Nagi; Raju, S <br/> <br/>Abstract: Synthesis of isoxazolyl quinoline-3-carboxamides <b style="">3</b> and isoxazolyl-1,4-benzothiazine-2-carboxamides <b style="">4</b> have been accompli­shed by cyclocondensation of isoxazolyl-3-oxo-butanamides <b style="">2</b> with <i style="">o</i>-amino benzaldehyde or <i style="">o</i>-amino thiophenol involving Friedelander’s condensation and oxidative cyclization respectively. <br/> <br/>Page(s): 1144-1150 Thu, 29 Jul 2010 22:58:59 GMT Mixed ligand cobalt(II) complex as an efficient catalyst for oxidative deoximation using hydrogen peroxide http://nopr.niscair.res.in/handle/123456789/10087 Title: Mixed ligand cobalt(II) complex as an efficient catalyst for oxidative deoximation using hydrogen peroxide <br/> <br/>Authors: Das, Pranab J; Das, Amal; Baruah, Akashi <br/> <br/>Abstract: Mixed ligand cobalt(II) complexes having an amino acid as a ligand are reported to catalyze the decomposition of hydrogen peroxide. This property was utilized for carrying out an easy and efficient deoximation of oximes to the corresponding carbonyl compounds. <br/> <br/>Page(s): 1140-1143 Thu, 29 Jul 2010 22:58:59 GMT
