Abstract: Using a one-pot, three-component approach, we synthesised 25 dihydropyrrol-2-one and two 5-oxo-2,5-dihydrofuran compounds, each featuring two trifluoromethyl groups. This method emphasises timeliness and cost-effectiveness, crucial in drug development. Structural verification was conducted using NMR, FT-IR, MALDI-MS, single-crystal, and powder XRD. The antibacterial and antifungal activities of these compounds were evaluated on yeasts (Candida sp.) and bacteria, including Gram-positive (Staphylococcus aureus, a significant opportunistic pathogen, being more susceptible than S. epidermidis) and Gram-negative strains. Compounds with o-OH and m′-NO2 groups exhibited superior activity, while those with p-OH and m-OMe groups showed slightly lower but still significant activity. For furan structures, Candida albicans displayed greater sensitivity than C. parapsilosis. Additionally, 13 compounds demonstrated haemolysis below 5%, indicating low toxicity.
