El-Agrody, A. M. published the artcileReactions of benzopyran-2-one-3-carbonyl derivatives with nucleophilic reagents, HPLC of Formula: 54385-49-8, the main research area is carbethoxycoumarin reaction phenylenediamine aminophenol; coumarincarbonyl chloride reaction nucleophilic reagent; azaindenylcarbonylcoumarin; benzimidazolylcoumarin; benzoxazolylcoumarin.
Several benzopyran-2-one-3-carboxamides have been prepared by the condensation of coumarin-3-carbonyl chloride with various nucleophilic reagents. The reaction of 3-carbethoxycoumarin with o-phenylenediamine and o-aminophenol gave 3-(benzimidazolyl)- and 3-(benzoxazolyl)coumarins. The reaction of 3-(bromoacetyl)coumarin with 3-cyano-4,6-dimethylpyridine-2-thiol in the presence of K2CO3 gave I.
