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.
