Electrolysis of 2-oxa- and 2,5-dioxabicyclo[n.4.0]alk-1(6)-enes (n = 4, 10) under conditions of direct undivided anodic oxidation in methanol results in their electrochemical mono- and dimethoxylation; electrolysis of the corresponding 2-oxa- and 2,5-dioxabicycloalkanes involves electrochemical cleavage of the bridging carbon-carbon bonds followed by electrooxidative transformation into methyl omega-(2-methoxytetrahydrofuryl)-, omega-(dimethoxymethyl)-, and omega-(1,3-dioxolan-2-yl)alkanoates.
