Reaction of 2-pyrrole carboxylates with Lawesson's reagent at elevated temperatures results in the corresponding thionoesters, concurrent with the production of a new class of pyrrole annulated with the (1,3,2)-thiazaphospholidine unit.
Due to the prevalence of thioamides in antibacterial compounds, we chose to convert the amide in the antitubercular compound 2-(decylsulfonyl)acetamide to a thioamide using Lawesson’s reagent to study its activity against a range of microorganisms. This derivative (8) had significantly diminished activity against tuberculosis but slightly better activity than the parent compound against the Gram positive species Staphylococcus aureus. This activity against a second major pathogen is remarkable considering the structural simplicity of these compounds.
