Abstract (+)-Guaiacin, a trans(2,3)-trans(3,4) phenyltetralin lignan, has been isolated for the first time from the stem bark of Machilus edulis King (Lauraceae) together with dihydroguaiaretic acid. Contrary to earlier observations, (+)-guaiacin has been converted by two different routes to (+)-galbulin, a new optical antipode of (−)-galbulin. Physical properties including NMR and MS data as well
摘要 (+)-Guaiacin 是一种反式(2,3)-反式(3,4) 苯基四氢化萘木脂素,首次与二氢愈创木酸一起从樟科植物的茎皮中分离得到。与早期的观察相反,(+)-愈创木酚已通过两种不同的途径转化为 (+)-galbulin,一种新的 (-)-galbulin 光学对映体。首次报道了这些木脂素的物理性质,包括 NMR 和 MS 数据以及化学降解反应。
