Quantitative reaction cascades of ninhydrin in the solid state
Crystalline ninhydrin (1) undergoes waste-free solid-state cascade reactions with dimedone, L-proline, three o-phenylenediamines, o-mercaptoaniline, two ureas, three thioureas, and methyl 3-aminocrotonate. The yields are quantitative and give pure crystal
Synthesis and anticonvulsant activity of some 2,4-disubstituted-2,4-benzodiazocine-1,3,5,6-tetrones, 1-mono and 1,3- disubstituted indenoimidazoles and 2-substituted imidazoisoindoles
1-Mono and 1,3- disubstituted indeno[1,2-d] imidazolones were synthesized by reaction of appropriately mono- and disubstituted ureas with ninhydrin, in aqueous alcohol and heat. Oxidation of these with sodium metaperiodate formed the corresponding imidazo
