A synthesis of the tetrahydrofuran lignan (±)-agastinol, starting from the cheap Vanillin, has been developed based on Stobbe reaction with diethyl succinate to give the skeleton of lignan, which was then reduced to afford meso- and threo-(±)-secoisolanciresinol. threo-(±)-Secoisolanciresinol was treated with DDQ in acetic acid to give the 2-aryl tetrahydrofuran lignan, and which was then condensed
四氢呋喃木脂素 (±)-agastinol 的合成,从廉价的香兰素开始,基于与琥珀酸二乙酯的 Stobbe 反应得到木脂素的骨架,然后将其还原以提供中-和苏-(±)-十二异山环树脂醇。苏-(±)-Secoisolanciresinol 在乙酸中用DDQ 处理得到2-芳基四氢呋喃木脂素,然后与阿魏酸缩合得到(±)-agastinol。
