Synthesis of 2-Acetyl-5,8-dihydro-1,4-dihydroxy-3-methyl Naphthalene: A Product from the Isomerisation of Diels-Alder Adducts of Both 5-Methyl- and 6-Methyl-2-acetyl-1,4-benzoquinone with 1,3-Butadiene

2-Acetyl-5,8-dihydro-1,4-dihydroxy-3-methyl-naphthalene was synthesised via Diels-Alder addition of 2-acetyl-3-methyl-1,4-benzoquinone to buta-1,3-diene followed by enolisation. It was identical with material obtained by pyridine-induced acetyl migration from the 1,3-butadiene adducts of both 3- and 6-methyl-2-acetyl-1,4-benzoquinone.
2-乙酰基-5,8-二氢-1,4-二羟基-3-甲基-萘是通过2-乙酰-3-甲基-1,4-苯醌与丁-1,3-二烯的狄尔斯-阿尔德加成合成的随后进行烯醇化。它与通过吡啶诱导乙酰基迁移从 3-和 6-甲基-2-乙酰基-1,4-苯醌的 1,3-丁二烯加合物获得的材料相同。
