An asymmetric variant of the hydrozirconation reaction has been established starting from Boc-protected chiral allylic amines. The resulting diastereoselectively formed N-functionalized organozirconiums can be considered as promising chirons. In this case, they have transformed into enantiomerically enriched cis-2,3-disubstituted azetidines through a iodination/cyclization sequence.
