4-disubstituted furans via mono-S-ipso-substitution. The ability of 3-methylthio and 3-phenylthio substituents for directing the metallation at position α-relative to the substituent has allowed the regiospecific alkylation. It provides a straightforward approach to several 3-monothiosubstituted furans which are receiving increasing interest as odour and flavour chemicals.
A nickel-catalyzed decarbonylative thioetherification of carboxylic acids with thiols was developed. Under the reaction conditions, benzoic acids, cinnamic acids, and benzyl carboxylic acids coupled with various thiols including both aromatic and aliphatic ones produce the corresponding thioethers in up to 99% yields. Moreover, this reaction was applicable to the modification of bioactive molecules
