Sažetak

The synthesis of DL-trans-2-amino-11,3-dihydroxy-4-eicosenes (VII)
by condensation of 2-octadecyne-1- al (IV) with nitroethanol in ihe
presence of potassium carbonate and subsequent reduction of the
two nitrodiols (V) is described. The resolution of the DL-threo - base
(VIIa) into the optical isomers was effected with D-tartaric acid.
The DL - erythro-base (VIIb) was resolved with L-glutamic acid.
N atural C20-sphingosine i s most probably the trans-D( -t-) - erythrobase.
