(+)-aristoteline ((+)-6) into other metabolites which had been isolated from Aristotelia species was investigated. Thus, treatment of (+)-6 with I2 as the single oxidant furnished the naturally occurring indole alkaloids (+)-makonine ((+)-9),(+)-aristotelinone ((+)-11), or (+)-11, 12-didehydroaristoteline ((+)-7) in good yields, the selectivity of the oxidation process depending on the chosen reaction conditions.
研究了合成的(+)-马兜铃啉((+)- 6)氧化转化成其他代谢物的过程,这些代谢物已从亚里斯多德氏菌属物种中分离出来。因此,用I 2作为单一氧化剂对(+)- 6的处理提供了天然存在的吲哚生物碱(+)-酮可宁((+)- 9),(+)-马兜铃酮((+)- 11)或( +)-11,12-二氢氢化马兜铃啉((+)- 7)收率高,氧化过程的选择性取决于所选的反应条件。
