合成路线1
该中间体在本合成路线中的序号：(IX)Silylation of 1-O-benzylglycerol (I) with tert-butyldimethylsilyl chloride afforded the 1,3-diprotected glycerol (II). After methylation of the free secondary hydroxyl of (II) using MeI and NaH to yield (III), its O-benzyl protecting group was cleaved by hydrogenolysis, yielding (IV). Acylation of alcohol (IV) with oleoyl chloride (V) in the presence of pyridine provided the corresponding ester (VI). Desilylation of (VI) to give alcohol (VII) was carried out by treatment with tetrabutylammonium fluoride. Alcohol (VII) was then condensed with (2-cyanoethyl)-N,N,N',N'-tetraisopropylphosphorodiamidite (VIII) in the presence of 3-hydroxypropionitrile and tetrazole, followed by reaction with elemental sulfur to furnish the thiophosphate (IX). Finally, cleavage of the cyanoethyl ester groups with Et3N and bis(trimethylsilyl)acetamide provided the title compound.
