Abstract: The present invention relates to a method for the production of d-erythro-sphingosine and analogs thereof, wherein the method comprises a step of condensing a compound of formula (2): or a salt thereof, wherein R1 is hydrogen, a C1-50 alkyl, preferably a C1-15 alkyl, more preferably a C10-15 alkyl, which may be saturated or contain one or more double and/or triple bonds, and/or which may contain one or more functional groups, the functional group being preferably selected from the group consisting of an alkoxy group, a secondary, or tertiary amine, a thioether, an acyloxy group, an acylamido group, a phosphorus containing functional group, a carboxyl group, or a carbonyl group, with a compound of formula (3): wherein the bond represents a double or a single bond, W is C, or C(OR4), Z is O, or OR5, provided that: when W is C, the bond is a double bond and Z is O, or when W is C(OR4), the bond is a single bond and Z is OR5, and wherein R2 and R3 are independently selected from a saturate
