Triphenylphosphine mediated synthesis of functionalized aryl-vinyl ethers from7-hydroxy coumarin and methyl acetylene carboxylate
7-hydroxy coumarin undergoes neutral conditions with alkyl propiolates in the presence of triphenylphosphine, and bysubstituation the corresponding aryl vinyl ethers was obtained in good yields
متن کاملSynthesis and characterization of some new 4-hydroxy-coumarin derivatives.
Some novel coumarins were synthesized starting from 4-hydroxycoumarin and methyl bromoacetate. The structures of the newly obtained compounds were confirmed by elemental analysis, mass, IR and NMR spectra.
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولEvaluation of in-vitro antimicrobial activity of some newly synthesized 7-hydroxy 4-methyl coumarin congeners
A series of substituted 8-arylazo 7-hydroxy 4-methyl coumarin (4a-4g) were synthesized and in-vitro evaluation for their preliminary antibacterial activities against E.coli, Staphylococcus aurous, Bacillus subtilis and Pseudomonas aeroginosa were carried out by agar-well diffusion method. Initially, the diazotized primary aryl amines, 3a-3g were synthesized and followed by coupling with 7-hydro...
متن کاملSynthesis and Evaluation of Antimicrobial Activity of Metal Complexes of 4-(2'-Hydroxy Phenyl Imino) Phenyl Sulphonamide
Keeping in view the promising potential of carbonic anhydrase inhibitor based antimicrobials and enhancement of carbonic anhydrase inhibitory activity by metal complexes of sulfonamides, with an aim to develop better antimicrobial agents we have attempted investigation of antimicrobial activity of metal complexes of 4-(2'-hydroxy phenyl imino) phenyl sulphonamide. Sulfanilamide was taken...
