摘要:
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 the 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.
摘要:
The invention relates to a method for reducing the quantity of an unsaturated cyclic imine (I) of formula (I) in a mixture containing hexamethylenediamine and an imine (I), R1 meaning an alkenyl radical with 3, 4, 5, 6, 7, 8, 9, 10, 11 carbon atoms belonging to the ring system, by electrochemically converting the imine (I) into a saturated cyclic amine of formula (II) in the presence of solvated protons.
