function with an acidic NH group were prepared using the direct insertion of zinc dust into the corresponding alkyl iodides in THF or THF:DMSO mixtures. Most of the starting iodides were obtained from natural α-amino acids and the resulting zinc species afforded after transmentalation with CuCN·2LiCI and reaction with a selection of relatively reactive electrophiles a variety of polyfunctional 1,2-amino

The 3-azabicyclo[3.1.0]-hexane ringsystem was constructed in a convergent one-pot procedure starting from readily available starting materials, using the intramolecular tandem Michael-SN2 reaction. The methodology was also extended to the synthesis of 3-azabicyclo[4.1.0]heptane ringsystem.
