Chemistry and application of 4-oxo-4H-1-benzopyran-3-carboxaldehyde
TL;DR: The chemistry and application of the title aldehyde and some simple derivatives thereof are reviewed in this paper, where the authors propose a simple derivative of the aldehydes, which they call simple aldeheeds.

Effect of Microwave Irradiation on the Condensation of 6-Substituted 3-Formylchromones with Some Five-membered Heterocyclic Compounds
TL;DR: In this article, the effect of microwave irradiation on the condensation of 3-formylchromones with 2-imino-1-methylimidazolidine-4-one (creatinine), 2-thioxoimidazlinine-1.4-oxobenzopyrans (thiohydantoin), and 3-ethylrhodanine (3-ethyl rhodanines) was investigated.
Journal ArticleDOI
Discovery of new chromone containing sulfonamides as potent inhibitors of bovine cytosolic carbonic anhydrase.
TL;DR: Series of chromone containing sulfonamides were prepared by the reaction of (un)substituted 3-formylchromones with 3-aminobenzenesulfonamide and 4-amino-3- formyl chromones with bCA inhibitory activity determined.

A facile route to phenyl, phenylsulfanyl and phenylselanyl substituted pyrano[3,2-c]chromenes
TL;DR: The synthesis of phenyl, phenylsulfanyl and phenylselanyl substituted pyrano[3,2-c ]chromenes is accomplished via cyclocondensation of 4-oxo-4 H -chromen-3-carbaldehydes 1 with appropriately substituted acetic acids 2 under mild conditions as discussed by the authors.
