2) The condensation of the previously described aldehyde (XI) with (S)-(+)-2-acetoxy-1,1,2-triphenylethanol (XX) by means of lithium diisopropylamide (LDA) in THF gives 5-[2-(4-fluorophenyl)-5-isopropyl-3-phenyl-4-(N-phenylcarbamoyl)pyrrol-1-yl]-3(R)-hydroxypentanoic acid 2-hydroxy-1(S),2,2-triphenylethyl ester (XXI), which is trans-esterified with sodium methoxide in methanol/THF yielding the expected methyl ester (XXII). The condensation of (XXII) with tert-butyl acetate (XXIII) by means of LDA in THF affords (R)-7-[2-(4-fluorophenyl)-5-isopropyl-3-phenyl-4-(N-phenylcarbamoyl) pyrrol-1-yl]-5-hydroxy-3-oxoheptanoic acid tert-butyl ester (XXIV), which is reduced with triethylborane and NaBH4 in THF, hydrolyzed with NaOH, lactonized by heating in refluxing toluene and finally submitted to fractional crystallization in order to separate the two diastereomers of the obtained lactone, (R,R) and (R,S). The (R,R)-diastereomer (XIX), already obtained, is finally treated with NaOH and then with CaCl2.

The synthesis of atorvastatin [14C]-labeled on the side chain has been described: The reaction of [14C]-labeled sodium acetate (I) with phthaloyl chloride (II) in refluxing xylene gives the acyl chloride (III), which is treated with 1,2,2-triphenyl-1(S),2-ethanediol (IV) in dichloromethane yielding the expected monoacetate (V). The condensation of (V) with the pyrrolepropionaldehyde (VI) by means of lithium diisopropylamide (LDA) in THF affords the chiral beta-hydroxyester (VII), which is transesterified with sodium methoxide in methanol providing the corresponding methyl ester (VIII). The condensation of (VIII) with tert-butyl acetate (IX) by means of LDA in THF gives the beta-oxo-delta-hydroxyester (X), which is regioselectively reduced to the dihydroxyester (XI) by means of BEt3, NaBH4 and H2O2 in THF. The hydrolysis of (XI) with NaOH in THF/water, followed by acidification yields the free acid (XII), which is heated in refluxing toluene in a Dean-Stark trap to provide lactone (XIII). The reaction of (XIII) with NaOH in THF/methanol gives the corresponding sodium salt (XIV), which is finally treated with CaCl2 in the same solvent.
