The tandem reaction of α,β-unsaturated aldehydes with trimethylsilyl azide and 2,2,6,6-tetramethylpiperidin-1-yloxy in the presence of chiral amines and iron complexes as the catalysts in a one-pot reaction enantioselectively afforded β-azido α-oxyaminated aldehydes. Further synthetic modification of the product afforded β-aminoα-hydroxyesters in good yields with good diastereo- and enantioselectivities
