9-diazo-1-methoxy-9H-fluorene, which inhibits the proliferation of HeLa cells, was achieved in reasonable chemical yield. In addition, various diazofluorenes were synthesized using the above protocol and their antitumor effects were evaluated. As a result, several novel diazofluorenes, which have a stronger cytotoxic activity than cisplatin against various human epithelial cancer cells, were found.

A novel approach to aryl or alkenyl nitriles from benzyl and allyl halides has been developed. A tandem TBAB-catalyzed substitution and the subsequent novel oxidative rearrangement are involved in this transformation. To the best of our knowledge, this is the first transformation from allyl halides to alkenyl nitriles. The broad reaction scope and the mild conditions may make these methods of use in organic synthesis.
