A diastereoselective synthesis of racemic d/l-erythro-sphingosine is described. The approach involves employing tethered aminohydroxylation (TA) to introduce the 2-amino and 3-hydroxy functions with required stereochemistry. sphingolipids - sphingosine - ceramide - amino alcohols - diasteroselectivity
A general protocol for the enantioselectivesynthesis of 3-heterosubstituted-2-amino-1-ols was developed based on metal- free intramolecular regio- and stereoselective diene aziridination and regioselective opening. Kinetic resolution of the resulting (1'-NR1 R2 and 1'-SR)-4-oxazolidinones was performed using ABCs organocatalysts, expanding the application of this methodology.

D-erythro-sphingosine () and the 3-amino-2-hydroxy-L-erythro isomer were synthesized in a highly enantio- and regioselective manner by a modified Sharpless asymmetric epoxidation.

Starting from a vinylepoxide, a short and practical synthesis of D-erythro-sphingosine is described. The key transformations are a regioselective opening of the vinylepoxide and an E-selective cross-metathesis, affording the target molecule in 5 steps and 51% overall yield.

An asymmetric sulfur ylide reaction was employed to prepare an epoxide intermediate in a convergent manner. This epoxide was efficiently transformed into D-erythro-sphingosine.
