Abstract: A method for the production of 3-hydroxy-3-methyl-penta-1,4-dienyl-substituted oxo-cyclohexane or oxo-cyclohexene derivatives involves cathodic reduction of the corresponding 3-hydroxy-3-methyl-pent-4-en-1-ynyl derivative in a split or quasi-split electrolytic cell at pH 2-9. A method for the production of compounds of formula (I) or (I') involves the cathodic reduction of compounds of formula (II) in a split or quasi-split electrolytic cell at pH 2-9. R = oxo-cyclohexyl or oxy-cyclohexenyl (both optionally substituted with hydroxyl, alkoxy and/or alkyl groups), the oxo groups being in the form of an acetal, ketone or enol ether; R = a hydroxyl group or a protecting group which can converted into OH by hydrolysis. An Independent claim is also included for an electrolytic cell for use in this process in which the working electrode is made of solid graphite, sheets of graphite felt or carbon felt, woven fabric with carbon-coated electrolyte-contact surfaces, carbon-filled porous solids, or porous metal.

Abstract: The invention relates to a method for producing compounds of general formula (I), wherein Rl represents an oxocyclohexyl radical which is optionally substituted by a hydroxyl radical, an alkoxy radical, and/or alkyl radicals, or an oxocyclohexenyl radical which is optionally substituted by a hydroxyl radical, an alkoxy radical, and/or alkyl radicals, the oxo groups being in t he form of an acetal, a ketone, or an enol ether, and R2 represents a hydroxy group or a protective group which can be transformed into a hydroxy group by means of hydrolysis. A compound of general formula (II) is cathodically reduced in a divided or partially divided electrolysis cell at a pH value of between 2 and 9.

An Independent claim is also included for a method for the production of cyclohexene derivatives of formula (I) or (II) by reduction of alkynes of formula (III) or (IV) using, as reducing agent, a mixture of zinc and at least one compound (B) selected from ammonium salts, copper salts, alkali metal salts and alkaline earth metal salts. R = a group of formula R1a, R1b, R1c or R1d; R = OH or a protecting group which can be hydrolysed to OH; R , R = H or 1-4C alkyl; and R = H or 1-4C acyl.
