The syntheses of all stereoisomers of tetrasubstituted tetrahydrofuran lignan were accomplished, and the antimicrobial activity was examined. The 9,9′-diol compound bearing (7R,7′R,8R,8′R) and (7R,7′S,8R,8′R) stereochemistry showed the strongest antibacterial activity against Listeria denitrificans and Bacillus subtilis, respectively. It was also found that (−)-virgatusin bearing (7S,7′R,8S,8′S) stereochemistry had strongest antifungal activity.
