A practical two pot synthesis of N-arylpiperazinones from the corresponding aniline is described. The key transformation is a selective intramolecular Mitsunobu cyclodehydration of an amidoalcohol intermediate. A series of N-arylpiperazinones were prepared in yields up to 89%.

We have developed compounds that prevent farnesylation of Cryptoccoccus neoformans Ras protein by inhibiting protein farnesyltransferase with 3–4 nanomolar affinities. Farnesylation directs Ras to the cell membrane and is required for infectivity of this lethal pathogenic fungus. Our high-affinity compounds inhibit fungal growth with 3–6 micromolar minimum inhibitory concentrations (MICs), 4- to 8-fold
