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.
通过相应的α,β-二苄基-γ-丁内酯(合成来源的木脂素)的α-羟基化获得标题化合物,并将其与(±)-甲基trachelogenin 9相关联,后者的相对结构通过X射线结晶成像法确定。因此,(-)-Trachelogenin 1和(-)-nortrachelogenin 12具有(8S,8'S)绝对构型,而(+)-nortrachelogenin 20(或wikstromol)具有(8R,8'R)绝对构型。
