Synthesis of a Glycosylphosphatidylinositol Anchor Bearing Unsaturated Lipid Chains
摘要:
A GPI anchor bearing unsaturated fatty acid lipid chains (1) was synthesized by a highly convergent strategy employing the para-methoxybenzyl group for permanent hydroxyl protection. The final global deprotection was achieved by an efficient three-step, one-pot procedure to give an 81% isolated yield of the target structure.

The first totalsynthesis of a glycosylphosphatidylinositol (GPI) anchor bearing a polyunsaturated arachidonoyl fatty acid is reported. This lipid is found in mammalian GPIs that do not undergo lipid remodeling, a process that has important implications in the localization and function of GPI‐anchored proteins. Incorporation of the oxidation‐ and reduction‐sensitive arachidonoyl lipid in the target
