- Synthesis of γ-Lactones via the kowalski homologation reaction: Protecting-group-free divergent total syntheses of eupomatilones-2,5,6, and 3- epi-eupomatilone-6
-
A highly efficient synthesis of functionalized chiral γ-butyrolactone scaffolds has been described. The basis of the approach is the Kowalski ester homologation that is modified for our proposed transformation. The newly developed methodology combines a d

- Antimicrobial activity of stereoisomers of butane-type lignans
-
The relationship between the stereochemistry and antimicrobial activity of butane-type lignans was clarified. All stereoisomers of dihydroguaiaretic acid (DGA) showed both antibacterial and antifungal activity. The (+)- and (-)-7,7'-dioxodihydroguaiaretic
