All four 7αH-guaia-4,11-dien-3-one diastereomers have been synthesized from the common intermediate 1αH,10α-acetoxy-7αH-guaia-4,11-dien-3-one obtained from (+)-dihydrocarvone. The spectral features of the four diasteromers have been correlated and the structure and absolute configuration of 1βH,10βH,7αH-guaia-4,11-dien-3-one isolated from Pleocarphus revolutus has been confirmed.
所有四个7α ħ -guaia -4,11-二烯-3-酮非对映体已被从共同中间体1α合成ħ,10α -乙酰氧基- 7α ħ -guaia -4,11-二烯-3-酮从获得的(+) -二氢香芹酮。四个非对映体的光谱特征已被相关的结构和1β的绝对构ħ,10β ħ,7α ħ -guaia -4,11-二烯-3-酮从分离Pleocarphus revolutus已被证实。
