The Claisen rearrangement of 1-methyl-2-[(3-methylphenoxy)methyl]cyclopentene in N,N-dimethylformamide gave 5-methyl-2-(1-methyl-2-methylenecyclopentyl)phenol(5) via its trimethylsilyl ether. The methylation of 5, followed by a Simmons-Smith reaction and by the catalytic hydrogenolysis, afforded 3-hydroxycuparene.
1-甲基-2-[(3-甲基苯氧基)甲基]环戊烯在N,N-二甲基甲酰胺中的克莱森重排通过其三甲基甲硅烷基醚得到5-甲基-2-(1-甲基-2-亚甲基环戊基)苯酚(5)。5 的甲基化,然后是 Simmons-Smith 反应和催化氢解,得到 3-羟基铜烯。
