Abstract

On stirring an equimolar mixture of 4-oxo-4 H-chromene-3-carbaldehyde, ninhydrin and cyclohexyl isocyanide in CH2Cl2-MeOH (7:1) at room temperature produces 3-cyclohexylimino-1-(2-hydroxy-1,3-dioxo-2,3-dihydro-1H-inden-2-yl)-1,3-dihydro-9H-furo[3,4-b]chromen-9-one which on hydrolysis produces 1-(2-hydroxy-1,3-dioxo-2,3-dihydro-1 H-inden-2-yl)-1 H-furo[3,4- b]chromene-3,9-dione. The structure of the latter compound was confirmed by single crystal X-ray diffraction.
