The Pd-catalyzed allylic alkylation of thiocarboxylate ions was carried out with potassium thioacetate (KSAc) and potassium thiobenzoate (KSBz) and the racemic cyclic and acyclic carbonates rac-3aa, rac-3ba, rac-lda, rac-laa, rac-lba, and rac-lca, respectively (Scheme 2.1.4.21). The carbonates rac-3aa, rac-3ba, rac-lda, rac-laa, and rac-lba were treated with KSAc (1.4 equiv) or KSBz (2.0 equiv) in the presence of Pd(0)/L (2 mol%) and BPA (8 mol%) in CH2CI2/H2O. Under these conditions the acyclic carbonates rac-3aa and rac-3ba gave the thioesters 18aa, 18ab and 18ba, respectively (Table 2.1.4.14, entries 1-3), with high enantioselec-tivities in high yields [26]. 

Reist and coworkers [9,10] described the first sulfur-containing furanose rings. They prepared 4-thio-D-ribofuranose 14 (Figure 9.4) and 4-thio-L-ribofuranose via nucleophihc displacement of the tosylate in 2,3-(9-isopropylidene-4-(9-toluenesulfonyl-a-D- and -a-L-lyxopyranosides, respectively, with potassium thiobenzoate in DMF. Several nucleosides of 4-thiofuranoses were subsequently synthesized. For example, the 4 -thio analog 15 of natural thymidine and the corresponding derivative of cytidine were prepared by Whistler and coworkers [11].

L-Arabinose diethyl dithioacetal was converted, via its 2,3-<9-isopropylidene derivative 298 and its thiobenzoate 299, into 4-azido-4-dco. y-5-lliio-a-D-xylopyranose triacetate (300).- " Ditosylation of 297, displacement of the 5-tosyloxy group by treatment with potassium thiobenzoate, and exchange of the 4-tosyloxy group with sodium azide in DMF gave the 5-az.ido-4-.S -benzoyl-D-xj lose derivative 301, isolated as the main compound (65%) via a 4,5-episulfonium intennediate. 

The first preparation of a chalcogenocarboxylato copper complex was described in the article by Engelhardt et al. [62] in 1868, who prepared thioben-zoic acid copper from the reaction of potassium thiobenzoate with CUSO4 in aqueous solution. The chemistry of this class of compounds, however, is not...
