including proliferation, survival, and migration. For this reason the stereoselective syntheses of S1P and analogues are of great interest. Based on l-serine as source of chirality we achieved practical routes to prepare S1P (1) and the aryl group containing analogues 3 and 4 in fair amounts. The crucial stages of the syntheses are: introduction of the required side chain by addition of appropriate organometallics
鞘氨醇-1-
