DFO (1,8-Diazafluoren-9-one) is a new reagent for the detection of latent fingerprints. It reacts with amino acids present in fingerprints to give a fluorescent product, and is an improvement over ninhydrin which has been used in forensic laboratories for years. The object of this work was to synthesize new analogs of ninhydrin and DFO. The preparation of 9-Hcyclopenta[1,2-b:3,4-b'] dipyrazine-9-one (A) was attempted but was not successful. Currently the synthesis of 7H-cyclopenta[b]pyridine-S,6,7-trione (B) is being completed. The compound 9H-cyclopenta[1,2-b]pyrazine[3,4b] pyridine-9-one (C) will then be made from (B), an analog of ninhydrin.
