合成路线图解说明:

Treatment of 1,1,1-tris(hydroxymethyl)ethane (I) in DMF with NaH and docosyl bromide (II) in benzene yields 2,2,-bis(docosyloxymethyl) propanol (III), which is then condensed with pentaacetyl-2-chloro-2-deoxyneuraminic acid methyl ester (IV) (1) by means of Hg(CN)2 and HgBr2 in CHCl3 to provide the pentaacetylated compound (V). Hydrolysis of (V) by treatment with NaOMe and NaOH in THF:MeOH affords derivative (VI), which is finally converted into the target compound by reaction with sulfur trioxide-trimethylamine complex (SO3.(CH3)3N) in DMF followed by treatment with Dowex 50W-X8 (Na form) resin.
