One-Pot Oxidation of Alanine and Its Ethyl Ester with a Mild Oxidant 4′-Methylazobenzene-2-sulfenyl Bromide
摘要:
One-pot oxidation of alanine and its ethyl ester with a mild oxidant 4'-methylazobenzene-2-sulfenyl bromide is described. Using a nonreactively water-soluble electrophilic species, 4'-methylazobenzene-2-sulfenyl bromide, with L-alanine and its ethyl ester (in 3:1 molar proportions) in aqueous solution at room temperature, the corresponding sulfenimines are prepared. On hydrolysis in acidic medium at room temperature, these sulfenimines give ethanal and pyruvic acid respectively.
