STEREOSELECTIVE SYNTHESIS OF CIS-4-METHYLSPHINGOSINE AND DERIVATIVES THEREOF

摘要

The invention provides for synthesis of a (S-R) dihydroxy-amino-methylalkylene characterized by the general formula I, or its R-S diastereomer, wherein R1 is CH2OH or CH2-CH2OH, and R2 is C2 to C20 alkyl, whereby a compound characterized by the general formula II, with R3, R4 and R5 being protecting groups for amino and hydroxyl functions, respectively, is used as a starting material. The invention further provides novel intermediates for syntheses of, and analogues to, cis-4-methylsphingosine.
