The first systematic investigation into the Baeyer–Villiger reaction of an anthraquinone is presented. The double Baeyer–Villiger reaction of quinizarin dimethyl ether is viable, directly providing the dibenzo[b,f][1,4]-dioxocin-6,11-dione ring-system, which is otherwise difficult to prepare. This methodology provides rapid access to 1,2,3,4-tetraoxygenated benzenes, and has been exploited by application
提出了对蒽醌的Baeyer-Villiger反应的首次系统研究。奎尼沙林二甲醚的双拜尔-维利格反应是可行的,直接提供了二苯并[ b,f ] [1,4]-二恶英-6,11-二酮环系,否则很难制备。该方法可以快速获得1,2,3,4-四加氧苯,并已被用于天然存在的苯并二恶唑及其联苯二聚体的全合成,这两种方法均具有显着的生物学活性。有趣的是,发现轴向手性联苯是构型稳定的,但是拆分的对映异构体在αD-线处没有光学活性。
