The solvents were recycled and reused three times without noticeable decrease in reaction yields. A putative conformation of compound I [R1 = OMe, R2 = R3 = H, X = NMe] was determined using NMR spectroscopy and an ”anti” orientation of the fused aromatic rings was proposed. Moreover, some of the bis-(β-dicarbonyl)-methane derivatives I were tested for their antifungal activity against four Candida albicans strains. The biscoumarin I [R1 = H, R2 = R3 = OMe, X = O] and bisquinolinone I [R1 = OH, R2 = OMe, R3 = H, X = NMe] exhibited promising anticandidial activity. In parallel, in silico ligand-based similarity calculations provided a putative mechanism of action of the examined compounds through CYP51 inhibition.
