A series of pyrazole-fused isocoumarins were synthesized by the reaction of ninhydrin hydrate and arylhydrazones in the presence of bromodimethylsulfonium bromide (BDMS) at room temperature. The reaction has the advantages of mild conditions, simple operation, the ready accessibility of the catalyst, and short reaction times.

Key words: ninhydrin hydrate, arylhydrazones, pyrazole-fused isocoumarins, BDMS
