converted under various reaction conditions into a range of derivatives including the di- and tri-O-methyl ethers 10 and 11, a 3,4-dibenzyl-3-hydroxy-tetrahydrofuran 12, and its acetate 13. These derivatives undergo oxidative cyclisation with DDQ in acetic acid or trifluoroacetic acid to yield 1-aryltetralin, 1-arylnaphthalene, dibenzocyclooctadiene and spirodienone derivatives in reactions which provide biomimetic
gmelinol的氢解8与钠在液氨中给出了一个三醇9,这是在各种反应条件下转化成范围衍生物包括二-和三- ø -甲基醚10和11,3,4-二苄基-3-羟基四氢呋喃12及其乙酸酯13。这些衍生物在乙酸或三氟乙酸中与DDQ进行氧化环化反应,在反应中生成1-芳基四氢萘,1-芳基萘,二苯并环辛二烯和螺二烯酮衍生物,这些反应为木脂素的生物遗传转化提供了仿生类似物。
