Secondary and tertiary cyanoformamides have been synthesized with a solvent-free approach from carbamoyl imidazoles and TMSCN. This method negates the need to use large excesses of toxic reagents and is amenable to large-scale synthesis.
Treatment of primary amines with tetramethylphenylguanidine (PhTMG) and a cyanophosphonate at −10 °C under an atmosphere of carbon dioxide provides cyanoformamides in very high to excellent yields. The reaction proceeds efficiently within a short time. By-products were not detected in most runs and epimerization was not found when optically pure α-aminoesters were used as substrates. As an example, the reaction was applied to the synthesis of the marine natural product ceratinamine.

The present invention concerns compounds and their use to treat cell proliferative diseases such as cancer. Compounds of the present invention display significant potency as kinase inhibitors, cause the downregulation of c-myc, and inhibit the growth and survival of cancerous cell lines.
The Pd(0)-catalyzed intramolecular cyanoamidation of several unsaturated cyanoformamides with alkenyl, allenyl, and alkynylgroups was investigated. In the cases of alkynyl and 1,1-disubstituted alkenyl cyanoformamides, the Pd(0)-catalyzed C–CN activation and subsequent insertion reaction proceeded smoothly and gave the corresponding lactams bearing a cyano group at the β-position in good yields.
