4) Lactone form: The condensation of 2(S)-(chloromethyl)oxirane (XXXIII) with trimethylsilylacetylene (XXXIV) by means of butyllithium and BF3 ethearate in THF gives 5-chloro-4(S)-hydroxy-1-(trimethylsilyl)-1-pentyne (XXXV), which is cyclized with KOH in THF to the chiral epoxide (XXXVI). The condensation of (XXXVI) with 2-cyclopropyl-4-(4-fluorophenyl)-3-(phenylsulfanylmethyl)quinoline (XXXVII, see Scheme 5) by means of butyllithium in THF affords the silylated heptynol (XXXVIII), which is desilylated with K2CO3 in methanol to the terminal acetylene (XXXIX). The carboxylation of (XXXIX) with CO by means of PdCl2/CuCl2 in methanol yields the heptynoic acid ester (XL), which is selectively reduced with H2 over the Lindlar catalyst in methanol to the cis-heptenoic ester (XLI). The cyclization of (XLI) with PPTS in refluxing toluene affords the (S)-unsaturated lactone (XLII), which is oxidized with m-chloroperbenzoic acid to the corresponding sulfinyl derivative (XLIII).
