Not only rearrangement but also cyclization occurred in a Fries rearrangement of 1-methoxy-4-(4-methyl-2- and -3-pentenoyloxy)benzenes and gave 5,8-dihydroxy-4,4-dimethyl-3,4-dihydro-1(2H)-naphthalenone. The reduction and oxidation of the dihydronaphthalenone gave 5-hydroxy-8,8-dimethyl-5,6,7,8-tetrahydro-1,4-naphthalenedione and 8,8-dimethyl-7,8-dihydro-1,4,5(6H)-naphthalenetrione, respectively.
1-甲氧基-4-(4-甲基-2-和-3-戊烯酰氧基)苯的弗里斯重排不仅发生重排而且环化,得到5,8-二羟基-4,4-二甲基-3,4-二氢-1(2H)-萘酮。二氢萘酮的还原和氧化得到5-羟基-8,8-二甲基-5,6,7,8-四氢-1,4-萘二酮和8,8-二甲基-7,8-二氢-1,4,分别为 5(6H)-萘三酮。
