cation with 2,3-dimethyl-1,3-butadiene are cleaved by ozonolysis to furnish triketones. In the presence of methanolic KOH, these triones undergo tandem aldol additions to furnish centro-hydroxylated triquinacene skeletons.
通过臭氧分解裂解由Nazarov 2-氧化环戊烯基阳离子被2,3-二甲基-1,3-丁二烯捕获而获得的现成的[4 + 3]-环加合物,可通过臭氧分解法裂解得到三酮。在甲醇KOH的存在下,这些三酮经串联羟醛加成以提供中心羟基化的三喹并苯骨架。
