摘要：

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 alpha-position to the lactam nitrogen. Formation of the corresponding enamide by elimination of methanol followed by a diastereoselective dihydroxylation. diacetylation and subsequent regioselective reduction afford the orthogonally protected (3S,6R)-3-amino-6-hydroxy-azepan-2-one.
