The first total synthesis of the highly functionalized monoterpenoid indole alkaloid (+)-aristolone ((+)-2) is described. This investigation uncovered the hitherto unknown relative and absolute configuration of this rare metabolite which had been isolated before by others in ppm-amounts from Aristotelia australasica. Dehydration of synthetic (+)-2 led to a readily separable mixture of the two alkaloids
描述了高度官能化的单萜类吲哚生物碱(+)-马兜铃酮((+)- 2)的第一个全合成。这项研究揭示了这种稀有代谢物的迄今未知的相对和绝对构型,这种构筑物以前曾被其他人以百万分之几的量从Aristotelia australasica中分离出来。合成(+)- 2的脱水导致两种生物碱11,12-didehydro-10-oxomakomakine((+)- 3)和11,12-didehydro-10-oxohobartine((-)- 4)的易于分离的混合物)于1988年从A. chilensis中分离出来。
