Efficient preparation of S-aryl thioacetates from aryl halides and potassium thioacetate
摘要:
A method for the preparation of S-aryl thioacetates using palladium-mediated couplings of aryl bromides and aryl triflates with potassium thioacetate as an inexpensive thiol source was developed. Electron withdrawing groups, electron donating groups and heterocyclic substrates were tolerated in the reaction conditions, affording the corresponding products in good to excellent yields. This method was applied to the preparation of novel sulfone-containing DPP-IV inhibitors. (c) 2007 Elsevier Ltd. All rights reserved.

Abstract An unprecedented metal-, halogen- and solvent-free, MSAA-promoted S-carbonylation of thiols with feedstock acids has been developed. This new transformation provides an efficient and atom-economic strategy for the synthesis of thioesters in a single operation from readily available and inexpensive starting materials. The reaction avoids the use of expensive and hazardous coupling reagents

An efficient and convenient strategy for the preparation of diaryl sulfides via a Fe‐promoted direct sulfuracylation of 2‐naphthylamine using thioesters as bifunctional reagents is described. This synthetic strategy features high chemoselectivity, good substrate scope and functional group tolerance.

AbstractA variety of aliphatic and aromatic S-esters of thiocarboxylicacids have been tested for antimicrobial activity. The relationship between the chemical structure of the compounds R1SC(O)R2 and their toxicity for microorganisms has been revealed, and the effect of various functional groups on the antimicrobial properties has been shown.

yields, by using 1,10-phenanthroline as a ligand in toluene at 100 degrees C after 24 h. Under microwaveirradiation the time was drastically reduced to 2 h. Both procedures are simple and involve a low-cost catalytic system. This methodology was also applied to the "one-pot" synthesis of target heterocycles, such as 3H-benzo[c][1,2]dithiol-3-one and 2-methylbenzothiazole, alkyl aryl sulfides, diaryl
