合成路线1
该中间体在本合成路线中的序号:(XXIV)Selective deprotection of (XVIII) with trifluoroacetic acid in THF - water affords the primary alcohol (XIX), which is oxidized with oxalyl chloride and DMSO in dichloromethane to the aldehyde (XX). The protection of the aldehyde group of (XX) with propane-1,3-dithiol and BF3 gives the dithiane derivative (XXI), which is resilylated with TBS-SO3CF3 as before to the dithiane (XXII). The pivaloyl group of (XXII) is eliminated with LiAlH4 in THF yielding the alcohol (XXIII), which is finally treated with benzenesulfonyl chloride and then with ethyl diphenylphosphine oxide and butyllithium in THF to obtain the first building group, the phosphine derivative (XXIV).

合成路线2
该中间体在本合成路线中的序号:(XXIV)3) Coupling and cyclization process.- The condensation of the diphenylphosphine derivative (XXIV) with aldehyde (LI) by means of butyllithium in THF gives the hydroxy phosphine derivative (LII), which is treated with potassium hexamethyldisylazane (KHMDS) to afford dithiane (LIII). Partial desilylation of (LIII) with THF - water - trifluoroacetic acid gives alcohol (LIV), which is condensed with N-tert-butoxycarbonylpiperidine-2(S)-carboxylic acid (LV) by means of dicyclohexylcarbodiimide (DCC) and 4-(dimethylamino)pyridine in dichloromethane to yield the ester (LVI). Elimination of the dithiane ring of (LVI) with N-chlorosuccinimide and silver nitrate in anhydrous methanol affords the dimethyl acetal (LVII), which is hydrolyzed to the corresponding aldehyde (LVIII) with acetic acid. The condensation of (LVIII) with 4(S)-benzyl-3-[2-(4-methoxybenzyloxy)acetyl]oxazolidin-2-one (LIX) by means of dibutylboron trifluoromethylsulfonate in toluene gives the oxazolidone derivative (LX).
