The ability of enamines to form in situ generated radicals gives rise to an entirely new principle of activation and thus to a series of very usefijl and highly selective previously unknown C-C bond formation processes. Thus, enamine catalysis changed into SOMOsingly occupied molecular orbital) (Figure 4.2) [24]. For direct experimental evidence of an enamine radical cation in SOMO catalysis see Reference [25]. These types of transformations were extensively elaborated by the MacMillan group. The first steps in this new concept were accomplished by the formation of radicals of enamines of imidazoHdin-4-ones.
