In this paper, we report an efficient synthetic method for thioester formation from sodium thiosulfate pentahydrate, organic halides, and aryl anhydrides. In the one-pot two-step reactions developed in this study, sodium thiosulfate was used as the sulfur surrogate for acylation with anhydrides, followed by substitution with organic halides through the in situ generation of thioaroylate. Furthermore, two important organic compounds could be successfully synthesized using our developed method. The advantages of the one-pot two-step reactions are operational simplicity, structurally diverse products with 42%-90% yields, use of relatively low toxic and odourless reagents, and easy applicability to large-scale operation.

(6-Oxo-6H-pyridazin-1-yl)phosphoric acid diethyl esters (3) are efficient and selective coupling agents for equimolar esterification of carboxylic acids and alcohols. Esterification of aliphatic and aromatic carboxylic acids with aliphatic and aromatic alcohols using 3 afforded the corresponding esters chemoselectively in good to excellent yield.
New prodrugs of 9-(2-phosphonomethoxyethyl) adenine [PMEA]: Synthesis and stability studies
Benzaria,Gosselin,Pelicano,Maury,Aubertin,Obert,Kirn,Imbach
, p. 563 - 565 (2007/10/02)
The synthesis, and stability in different media of new PMEA prodrugs, with S-acyl-thioethyl (SATE) as enzyme-labile phosphonate protecting groups, are described in comparison with the already known Bis(POM)- and Bis(DTE)PMEA.
