We describe a practical synthesis of protected (3S,6R)-6-hydroxy-cyclolysine derivatives starting from cyclic L-lysine. Evaluation of the electrochemical oxidation of various protected amino-caprolactams allowed a regioselective electromethoxylation at the α-position to the lactam nitrogen. Formation of the corresponding enamide by elimination of methanol followed by a diastereoselective dihydroxylation
