A stereoselectivesynthesis of each of the four enantiomers of sphingosine from either L- or D-serine is reported here. The key steps in the sequence involve: (a) the diastereoselective addition of 1-lithiopentadecyne to aldehyde and (b) Mitsunobu inversion of propargyl alcohol .
Constrained ceramide analogs were designed and synthesized by binding terminal alcohol and amine of ceramide with additional carbonyl functional group as 3-acetyl (3), 3-propionyl (4), 3-benzoyl (5), and 3-hexadecanoyl-4-(1-hydroxyhexadec-2-enyl)-oxazolidin-2-ones (6). Compounds 4 and 5 showed potent antileukemicactivities against human leukemia HL-60 cells with good correlation between cell death
