Regio- and Stereoselective
Iodoamination of Ferrocene-Containing
Allenylphosphonates: Synthesis of Multifunctional Tetrasubstituted
Allylic Amines and Allylic Azides
A general
and practical methodology for the regio- and stereoselective
synthesis of multifunctional tetrasubstituted allylic amines and azides
based on iodoamination of ferrocene-containing allenylphosphonates
with anilines and sodium azide is described. A tetrasubstituted olefin
moiety, as well as an iodine atom, a phosphonate, and a ferrocene
group, are installed to the allylic amine motif simultaneously in
moderate to good yields.
