Resumen:
In conclusion, we have described an efficient conversion of dilithiated compounds, derived from bis(2-bromoallyl)amines, to dihydropyrrole derivatives by using TMEDA or catalytic amounts of CuCN, representing, as far as we know, the first intramolecular carbometalation of lithiated double bonds. In addition, a simple and straightforward synthesis of indoles has been also developed on the basis of this strategy. Further studies on the mechanism and synthetic applications of this novel transformation will be reported in due course.
