Deoxyvasicinone has been used as the key intermediate to prepare the alkaloids isaindigotone and luotonin A. This intermediate is directly converted into isaindigotone by condensation with 4-acetoxy-3,5-dimethoxybenzaldehyde; alternatively oxidation with SeO2 afforded the pyrrolo[2,1-b]quinazoline-3,9-dione, a putative precursor of the luotonin A.
