如方案IV中所概述的,制备了马兜铃生物碱(-)-别马兜铃碱(4)、(-)-锯齿碱(12)和(+)-马兜铃酮(13)。因此,通过Stevens的方法,通过Hg(NO3)2介导的Ritter反应将(1 S)-(-)-β-蒎烯(9)和3-吲哚基乙腈(10)偶联,然后还原所得亚胺,得到(+)-makomakine(11)。分子内Friedel-Crafts反应产生(+)-Aristoteline(3),其通过与氧和铂反应而被氧化。中间体氢过氧化物的还原递送生物碱12。碱催化骨架重排12得到生物碱13,用LiAlH 4还原得到仲醇14 a,b的混合物。将这些醇中的每一种用HCl在甲醇中处理得到(-)-别阿里斯特林(4)。
The Aristotelia alkaloids (-)-alloaristoteline (4), (-)-serratoline (12), and (+)-aristotelone (13) have been prepared as summarized in Scheme IV. Thus, via the method of Stevens, (1S)-(-)-beta-pinene (9) and 3-indolylacetonitrile (10) were coupled by a Hg(NO3)2-mediated Ritter reaction followed by reduction of the resulting imine to give (+)-makomakine (11). An intramolecular Friedel-Crafts reaction delivered (+)-aristoteline (3), which was oxidized by reaction with oxygen and platinum. Reduction of the intermediate hydroperoxide delivered alkaloid 12. Base-catalyzed skeletal rearrangement of 12 provided alkaloid 13, which was reduced with LiAlH4 to obtain a mixture of secondary alcohols, 14a,b. Treatment of each of these alcohols with HCI in methanol afforded (-)-alloaristoteline (4).
