合成路线1
该中间体在本合成路线中的序号：(VIII)The Diels-Alder reaction of butadiene (VIII) with acrylic acid (IX) gives cyclohexene-4-carboxylic acid (X), which by treatment with I2 and KI in water followed by a treatment with 1,5-diazabicyclo[4.3.0]non-5-ene (XI) in benzene is converted to 3-hydroxycyclohexene-5-carboxylic acid lactone (XII). The opening of (XII) with NaOMe in MeOH yields methyl 3-hydroxycyclohexene-5-carboxylate (XIII) as a mixture of isomers, which by treatment with phenylacetyl chloride (A) affords the corresponding phenylacetate (XIV), which by optical resolution and successive racemization of the residue with mercuric trifluoroacetate yields the active methyl 3-hydroxycyclohexene-5-carboxylate (XIIIa). The treatment of (XIIIa) with biphenylyl-4-carbonyl chloride gives the corresponding ester (XV), which is submitted to hydroxylation with OsO4-sodium chlorate yielding the glycol (XVI). Ring opening of (XVI) with sodium periodate in THF-water affords the dialdehyde (XVII), which is cyclized by treatment with pyrrolidine acetate (B) in benzene giving 5-methoxycarbonyl-3-(biphenylylcarbonyloxy)cyclopentene-1-carboxaldehyde (XVIII). The conjugate addition of (XVIII) with the vinyl cuprate (XIX) in HMPT-THF-ether at -78 C gives rise to 2-[3-(1-ethoxyethoxy)-1-octen-1-yl]-3-(4-biphenylylcarbonyloxy)-5-methyloxycarbonylcyclopentane-1-carboxaldehyde (XX), which is converted into the corresponding ethylene ketal (XXI) in the usual way (C).

合成路线4
该中间体在本合成路线中的序号：(IX)The chiral intermediate (1R,2S)-N-(tert-butoxycarbonyl)-2-fluorocyclopropylamine (III) is obtained as follows: 1) The cyclization of butadiene (IX) with dibromofluoromethane by means of BuONa, followed by oxidation with KMnO4, esterification with ethanol - sulfuric acid and reduction with tributyltin hydride gives 2-fluorocyclopropanecarboxylic acid ethyl ester as a cis/trans mixture (X), which is separated by crystallization. The cis-racemic-isomer (XI) is hydrolyzed with NaOH to the corresponding acid (XII), which is condensed with (R)-alpha-methylbenzylamine (XIII) by means of diphenyl chlorophosphate to give the mixture of diastereomers (XIV). This mixture is separated by crystallization, yielding pure (1S,2S)-2-fluoro-N-[alpha(R)-methylbenzyl]cyclopropanecarboxamide (XV), which is hydrolyzed with HCl to the corresponding free acid (XVI). Finally, this compound is converted into (III) by treatment with diphenylphosphoryl azide in refluxing tert-butanol.

该中间体在本合成路线中的序号：(VII)The reaction of the labeled acylated (+)-bornane-10,2-sultam (IV) with triethyl phosphite gives the phosphonate (V), which is treated with paraformaldehyde, galvinoxyl and K2CO3 yielding the acrylate derivative (VI). The cyclization of (VI) with butadiene (VII) by means of diethylaluminum chloride and galvinoxyl (as radical scavenger) affords the cyclohexene-carboxamide derivative (VIII), which is hydrolyzed with LiOH in THF/water giving the (1R)-3-cyclohexenecarboxylic acid (IX). The oxidation of (IX) with m-chloroperbenzoic acid and triethylamine in CCl4 yielded regioselectively the hydroxylactone (X), which is finally hydrolyzed with HCl to the labeled intermediate (I).

该中间体在本合成路线中的序号：(II)The intermediate (S)-3-(2-mesyloxyethoxy)-4-(triphenylmethoxy)-1-butanol mesylate (VIII) has been obtained as follows: The hetero Diels Alder cyclization of ethyl glyoxylate (I) with butadiene (II) in toluene at 160-70 C gives racemic 3,6-dihydro-2H pyran-2-carboxylic acid ethyl ester (III), which is submitted to enzymatic resolution by means of B.lentus protease, yielding a mixture of the hydrolyzed (R)-acid and unchanged (S)-ester (IV), that is easily separated. The reduction of the (S)-ester (IV) by means of LiAlH4 in THF affords the hydroxymethyl derivative (V), which is treated with Tr-Cl and DMAP in pyridine to provide the trityl ether (VI). Ozonolysis of the dihydropyran ring of (VI) by means of ozone and NaBH4 in dichloromethane/methanol gives (S)-3-(2-hydroxyethoxy)-4-(triphenylmethoxy)-1-butanol (VII). Finally this compound is treated with Ms-Cl and TEA in dichloromethane to yield the target intermediate (S)-3-(2-mesyloxyethoxy)-4-(triphenylmethoxy)-1-butanol mesylate (VIII). (see scheme no. 25239601a, intermediate no. (X).
