Indirect electrochemical methoxylation of N-acyl and N-carboalkoxy α-amino acid esters in α-position to nitrogen is possible, if chloride is used as mediator.The course of the reaction depends upon the protecting group as well as upon the amino acid side-chain.Increased electron withdrawing effects of the protecting group are accelerating the reaction.On the other hand aliphatic side-chains are diminishing the reactivity.High chloride ion concentrations improve the current yields surprisingly strong.
