Novel cyclohexanone derivatives of general formula: ##STR1## (wherein R.sup.1 is a hydrocarbon group of 1 to 15 carbon atoms) and new cyclohexanone derivatives of general formula: ##STR2## (wherein R.sup.1 and R.sup.2 each is a hydrocarbon group of 1 to 15 carbon atoms) are produced by an electrooxidative coupling of 1,3-cyclohexanedione with a vinyl ether of general formula: CH.sub.2 .dbd.CH-O-R.sup.1 (wherein R.sup.1 is as defined above) in the presence or absence of an alcohol of general formula: R.sup.2 OH (wherein R.sup.2 is as defined above). These new cyclohexanone derivatives can be easily converted to N-substituted or unsubstituted-4-oxo-4,5,6,7-tetrahydroindoles, which are of value as intermediates for the production of N-substituted or unsubstituted-4-hydroxyindoles and, thence, to pindolol and its analogs.
通用公式的新环己酮衍生物:##STR1##(其中R.sup.1是1到15个碳原子的碳氢基团)和通用公式的新环己酮衍生物:##STR2##(其中R.sup.1和R.sup.2分别是1到15个碳原子的碳氢基团)通过1,3-环己二酮与通用公式的乙烯醚进行电氧化耦合制备:CH.sub.2 .dbd.CH-O-R.sup.1(其中R.sup.1如上定义)在存在或不存在通用公式的醇:R.sup.2 OH(其中R.sup.2如上定义)的情况下。这些新环己酮衍生物可以轻松转化为N-取代或未取代的4-氧代-4,5,6,7-四氢吲哚,这对于生产N-取代或未取代的4-羟基吲哚及其衍生物,进而得到贝特诺洛尔及其类似物具有价值。
