Convenient synthesis of 3-vinyl and 3-styryl coumarins.

چکیده
A variety of 2-hydroxy aldehydes on reaction with 3-butenoic acid afford in a one-pot reaction the corresponding 3-vinylcoumarins. As expected, extension of the delocalized π-electron system accomplished by Heck coupling reactions with aryl halides results in an increased fluorescence of the compounds whose applicability is yet to be established.

متن کاملTandem aldehyde–alkyne–amine coupling/cycloisomerization: A new synthesis of coumarins
Cu-catalyzed A(3) coupling of ethoxyacetylene, pyrrolidine and salicylaldehydes led to a concomitant cycloisomerization followed by hydrolysis of the resultant vinyl ether to afford coumarins in a cascade process. The reaction proceeded through exclusive 6-endo-dig cyclization and is compatible with halo and keto groups giving coumarins in good to moderate yields.
متن کاملCoupled domino processes: synthesis of 3,5,8-trisubstituted coumarins from propargyl vinyl ethers.
The generation of a small and representative library of 3,5,8-trisubstituted coumarins (21 compounds, 7 families, 3 groups) is described. The library was built from the corresponding propargyl vinyl ethers and three different 1,3-dicarbonyl derivatives using a one-pot coupled domino strategy. These coumarins constitute a novel chemotype defined by the presence of a chemical handle in the pyrano...
متن کاملSynthesis of 4-(trifluoromethyl) coumarins using nano sulfated-titania as solid acid catalyst under solvent-free conditions
Nano sulfated titania was tested as solid acid heterogeneous catalyst for the synthesis of 4-(Trifluoromethyl) coumarin and coumarin derivatives under solvent-free condition. Factorial design evidenced a positive effect of reaction temperature, amount of catalyst, and solvents. This nano-sized sulfated titania has been prepared by a sol-gel hydrothermal process. The prepared sulfated titania s...
متن کاملEnzymatic synthesis of 8-vinyl- and 8-styryl-2'-deoxyguanosine modified DNA--novel fluorescent molecular probes.
Fluorescent analogs of the natural nucleobases are widely used as molecular probes for investigating DNA hybridization and topology. In this study the guanosine analogs 8-vinyl- and 8-styryl-2'-deoxyguanosine were synthesized and converted into the corresponding 5'-triphosphates. These C8 modified nucleotides were processed by various DNA polymerases to create fluorescent DNA. Whereas the 8-sty...
