The addition of Z-vinylic cuprates to enantiopure α-alkyl β-alkoxy aldehydes afforded syn allylic monoprotected diols in high diastereomerical purity. The sigmatropic rearrangement of trichloracetimidates derived from these monoprotected diols afforded protected allylic aminoalcohols which were oxidized into E-Alkene dipeptide isosteres.
