The methylene and sulfur analogues of sphingosine 1-phosphate labeled with a fluorescent group at the terminus of the backbone skeleton were stereoselectively synthesized as possible nonhydrolyzable visible ligands to the sphingosine 1-phosphate receptor, S1P1.
The syntheses of optically homogeneous sphingomyelin analogues, which possess CH2, NH, and S instead of the phosphate oxygen connecting the phosphocholine head group to the sphingosine backbone, were successfully achieved by employing the olefin cross-metathesis protocol between 1-pentadecene and the amino alcohol parts possessing the suitable building block or functional group for construction of
