,3,5-trimethylphenols or 2,3-dimethoxy-5-methyl-6-polyprenylhydroquinones were obtained selectively by the BF3·OEt2 catalyzed polyprenyl rearrangement of polyprenyl 4-acetoxy-2,3,5-trimethylphenyl ethers or polyprenyl 2,3-dimethoxy-4-hydroxy-5-methylphenyl ethers.
通过BF3·OEt2催化聚异戊二烯基4-乙酰氧基-2,3重排,选择性地获得4-乙酰氧基-6-聚异戊二烯基-2,3,5-三甲基苯酚或2,3-二甲氧基-5-甲基-6-聚异戊二烯基氢醌, 5-三甲基苯基醚或聚异戊二烯基 2,3-二甲氧基-4-羟基-5-甲基苯基醚。
