neolignan from was converted to a dibenzocyclooctadiene derivative by using two new reagents. The compound was further functionalized by the use of DDQ to mono- and dialcohols. Acid treatment of the monoalcohols led to oxidative demethylenation. The diols were converted to an epoxide and other rearranged products. The stereochemistry of the mono- and dialcohols was established based on nmr and cd spectral
通过使用两种新试剂将Austrobailignan-5(一种1,4-二芳基丁烷新木脂素)转化为二苯并环辛二烯衍生物。通过使用DDQ将化合物进一步官能化为一元醇和二元醇。一元醇的酸处理导致氧化脱甲基。二醇被转化为环氧化物和其他重排产物。一元醇和二元醇的立体化学是基于nmr和cd光谱数据建立的。
