A one-pot rearrangement of 2-(N-Alkyl-N-aryl)aminochromone-3-carbaldehyde to N-Alkyl-3-salicyloyl-2-quinolone - An antileishmanial agent

2-(N-Aryl)aminochromone-3-carbaldehyde does not show any change on heating in acetic acid, but under the same reaction conditions 2-(N-alkyl-N-aryl) aminochromone-3-carbaldehyde rearranges to 3-salicyloyl-2-quinolones, which exhibits antileishmanial activ

Rearrangements of N-alkyl-/aryl-nitrones derived from 4-oxo-4H-1- benzopyran-3-carboxaldehyde - A solvent-dependent process

C-(4-Oxo-4H-1-benzopyran-3-yl)-N-alkyl-/aryl-nitrones derived from 4-oxo-4H-1-benzopyran-3-carboxaldehyde, rearrange to 2-alkyl-/aryl-amino-3- formylchromone and/or 3-(alkyl-/aryl-aminomethylene)chroman-2,4-dione depending upon the reaction medium. 3-(Alkylaminomethylene)chroman-2,4-dione has been utilized in the synthesis of 1-benzopyrano[3,4-d]isoxazole-4-one.

Studies on chromone derivatives: Microwave assisted 1,3-dipolar cycloaddition reactions of 4-oxo-l-benzopyran-3-carboxaldehyde imine oxides

1,3-Dtpolar cycloadditioo reactions of chromone nitrones 1 have been carried out successfully under microwave irradiation. The reaction of nitrone 1 and alkene 2 proceeds regiospecifically at atmospheric pressure and the corresponding chromone linked isoxazolidines 3 are obtained in high yields.
