Application
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.
