Aplicação

Thioacetic acid (TAA) can undergo:
  • Enantioselective addition to nitroalkenes to form chiral 1,2-aminothiol derivatives in the presence of a novel sulfinyl urea organocatalyst. This method has been successfully employed in the synthesis of antifungal drug, sulconazole.
  • Asymmetric Michael addition reaction with chalcones in the presence of a bifunctional amine thiourea catalyst to form synthetically useful thioesters.
  • Asymmetric 1,6-conjugate addition with para-quinone methides in the presence of a chiral phosphoric acid catalyst to form chiral sulfur-containing diphenylmethane-type compounds.
  • Conjugate addition to methacrylamides with chiral trans-2,5-disubstituted pyrrolidine auxiliaries to form chiral β-mercaptocarboxylic acid derivatives.

Thioacetic acid is a reagent for introduction of the thiol group into organic molecules.

We studied the effects of polar groups on the gas-phase acidities of carboxylic acids experimentally and computationally. In this connection, the gas-phase acidities (DeltaH(acid), the enthalpy of deprotonation, and DeltaG(acid), the deprotonation free energy) of borane-complexed methylaminoacetic acid ((CH(3))2N(BH(3))CH(2)CO(2)H) and
