A new synthesis of ninhydrin and its ketals using iodobenzene diacetate
The oxidation of indene-1,3-dione (2) with iodobenzene diacetate-ROH-H2SO4, followed by the acid hydrolysis of the resulting 2,2-dialkoxyindane-1,3-diones (3), provides a new and convenient method for the synthesis of ninhydrin and its ketals.
