Anodic cleavage of several ketone N-phenylsemicarbazones into methyl N-phenylcarbamate and the corresponding dimethyl acetals

Several ketone N-phenylsemicarbazones were electrooxidized in the presence of potassium iodide and a base using methanol as the solvent to give nearly commensurate amounts of methyl N-phenylcarbamate and the corresponding dimethyl acetals. Continuous evolution of gaseous nitrogen was observed from the anolyte during the electrooxidation. The reactions were carried out under very mild reaction conditions and are presumed to proceed through a four-electron oxidation process, in which the iodide ion plays an important role as an electron carrier.

Isomerisation of 2-Alkoxycyclopropanecarboxylic Acids - An Effective Synthesis of 4-Oxo Carboxylic Acids

(Z/E)-2-Alkoxycyclopropanecarboxylic esters 2/3 were prepared from enol ethers 1 and ethyl diazoacetate.The saponification of these esters gives the corresponding (Z/E)-2-alkoxycyclopropanecarboxylic acids 4/5, which show stereomutation in water/methanol.This isomerisation was studied in labelled solvents and interpreted for the example of (E)-2-methoxy-2-phenylcyclopropanecarboxylic acid (5a).On heating in water/methanol the compounds 4/5 are transformed quantitatively into the corresponding 4-oxo carboxylic acids 6.
