The regioselective reaction of amines 7 at C-3 of optically active 2,3-epoxy-4-penten-1-ol (4) and its enantiomer 5 leads to 3-amino-4-pentene-1,2-diols of both the erythro-D- and -L-series, 8, 9. The scope of this process, mediated by titanium(IV) i

erythro-1-Amino-4-pentene-2,3-diols 7,8 of both the L- and D-series are readily accessible in high purity from 1,4-pentadien-3-ol via the 1,2-epoxy-4-pentenols 2, 4 by treatment with ammonia, primary aliphatic or aromatic amines, secondary aliphatic

Regioisomeric erythro-1- and -3-amino-4-pentenediols are available from 1,2-epoxy-4-pentenol 1 by aminolysis of 1 or of the rearranged 2,3-epoxypentenol 2. With adenine, D- and L-enantiomers of the nucleoside analogue 10 are obtained via the chloride
