Sigmatropic rearrangement of trichloracetimidates derived from syn monoprotected allylic diols 3 resulting from the condensation of vinylalanes or cuprates with α-alkoxyaldehydes afforded diastereomerically pure allylic amines 6. The oxidative cleavage of these amines allowed the access to α,α-disubstituted α-aminoacids in high enantiomeric purity.
