Oxidation peak potentials of sulfonamides and amidophosphates were measured in acetonitrile and compared with the corresponding amides and carbamates.The results showed that the order of easiness of oxidation was amides > carbamates > amidophosphates > sulfonamides.Furthermore, the reaction of silyl enol ethers or trimethyl phosphite with anodically α-methoxylated sulfonamides or amidophosphates has clearly shown that the α-methoxylated compounds are useful starting materials in organic synthesis.For example, optically active L-tryptophan was synthesized from α-methoxylated N-(p-tolylsulfonyl)-L-proline ester.
