This paper reports a new and simple procedure
for the synthesis of 3H-spiro[isobenzofuran-1,3?-pyrazole]
derivatives by reacting 1-benzylidene-2-phenylhydrazine
derivatives with ninhydrin in acetic acid medium at
room temperature followed by oxidative cleavage of their
corresponding dihydroindeno[1,2-c]pyrazoles.
