therapeutic agents againstmalaria has become urgent during the past few decades, due to an increased prevalence of drug-resistant strains of malaria-causing Plasmodium parasites. Possible targets are the hemoglobin-degrading asparticproteases, the plasmepsins. While acyclic α,α-difluoroketone hydrates have been introduced into peptidomimetics to bind to the catalytic Asp dyad of asparticproteases, alicyclic

A network of orthogonal COâ¯CO interactions was identified in the X-ray crystal structure of an α,α-difluorocyclopentanone derivative. This finding inspired investigations of self-association driven by these weak dipolar interactions in apolar solvents, which was proven by 1H NMR spectroscopy.
