摘要：

The antifungal activity, measured as minimum inhibitory concentration (MIC) of selected rr-substituted acetophenones, showed a linear correlation with the computed enolization energies (Delta E-enolization). This suggested that keto-enol tautomerization plays a significant role in the action mechanism of these or-substituted acetophenones. In order to corroborate this conclusion, two related compounds were synthesized which could not undergo keto-enol tautomerization. Their bioassay proved them to be completely inactive.
