以7-羟基-5-甲氧基香豆素(1a)为起始原料,经四步反应合成了5,7-二甲氧基香豆素类化合物,即从九里香根皮中天然提取的甘草烯(3b)和甘草二烯(2),总收率分别为45%和19%。
The 5,7-dimethoxycoumarins, gleinene (3b) and gleinadiene (2), which naturally occur in Murraya gleinei root bark, have been synthesized in four steps from 7-hydroxy-5-methoxycoumarin (1a) in overall yields of 45% and 19%, respectively.
