A new route for the construction of the mitosene skeleton was developed using 2-(diphenylphosphinyl)pyrrolidine (2) and 2-methoxy-3-methyl-1,4-benzoquinone (3) as starting materials. Regioselective oxidative addition of 2 to 3 gave 5-substituted pyrrolidinylbenzoquinone 4. Protection of the quinone function by reduction, followed by in-situ reaction with benzyl bromide, gave the bis-benzylated product
以2-(二苯基膦基)吡咯烷(2)和2-甲氧基-3-甲基-1,4-苯醌(3)为起始原料,开发了一条构造线粒体骨架的新途径。2至3的区域选择性氧化加成得到5-取代的吡咯烷基苯并醌4。通过还原保护醌功能,然后与苄基溴进行原位反应,得到双苄基化产物5。使用最近开发的吡咯并[1,2-a]吲哚的途径,将5转化为受保护的丝裂酮8。脱苄基反应和随后的8氧化反应产生了米托涅1个,产量高。
