WebMay 28, 2014 · Restricted rotations of chemical bonds can lead to the presence of persistent conformational chirality in molecules lacking stereocenters. We report the development of first-of-a-kind predictive rules that enable identification of conformational chirality and prediction of racemization barriers in the diarylether heptanoid (DAEH) natural products … In summary, a series of fenfuram-diarylether hybrids were designed, synthesized, and screened for their antifungal activities against five phytopathogenic fungi. Compound 1c with EC 50 values of 0.242 mg/L exhibited good antifungal activity against R. solani , superior to the controls.
