Abstract
Abstract The title compounds were obtained by α-hydroxylation of the corresponding α,β-dibenzyl-γ-butyrolactones (lignans of synthetic origin), and were correlated to (±)-methyltrachelogenin 9 whose relative structure was definitely established by X-ray cristallography. (-)-Trachelogenin 1 and (-)-nortrachelogenin 12 thus have the (8S,8′S) absolute configuration, whereas (+)-nortrachelogenin 20 (or wikstromol) has the (8R,8′R) absolute configuration.
