The disclosure provides therapeutic compositions (i.e., therapeutic agents) and methods of preventing or treating Friedreich's ataxia in a mammalian subject, reducing risk factors, signs and/or symptoms associated with Friedreich's ataxia (e.g., Complex I deficiency), and/or reducing the likelihood or severity of Friedreich's ataxia. The disclosure further provides novel intermediates for the production of said therapeutic compositions and related reduced versions of said therapeutic compositions, which reduce forms may also be used as therapeutic agents (or prodrugs of the therapeutic agent(s)).

A series of p-benzoquinones having an ester functional group in the α position of alkyl side chains was prepared. Irradiation of these quinones, except for methyl 3-methyl-2-(4-methyl-3,6-dioxo-1,4-cyclohexadienyl)-butyrate (3e), rapidly gave methyl 3-substituted 2,3-dihydro-5-hydroxybenzofuran-2-carboxylate in fairly good yields, and it was found that rearrangement of the side chain occurred concomitantly
制备了一系列在烷基侧链的α位具有酯官能团的对苯醌。这些醌的辐照,除了甲基 3-甲基-2-(4-甲基-3,6-二氧代-1,4-环己二烯基)-丁酸 (3e) 外,迅速得到甲基 3-取代的 2,3-二氢-5 -羟基苯并呋喃-2-羧酸酯的产率相当好,并且发现侧链的重排伴随发生。醌 3e 的光解得到 2-(2,5-二羟基-4-甲基苯基)-3-甲基-3-丁烯酸甲酯作为主要产物。假定中间体可以解释孤立的光产物。
