Zinca-ene-allene cyclization

The synthesis of polysubstituted pyrrolidines has been achieved344 in a diastereo-selective and enantioselective manner via the zinca-ene-allene cyclization. In an extension of this work,345 the zinca-ene-allene reaction of polysubstituted enynes lithiated on the propargylic position has been used to prepare polysubstituted... [Pg.541]
