文摘

A new catalytic method for the oxidation of substituted benzyl alcohols to the corresponding benzaldehydes by molecular oxygen using the enzyme/cofactor system laccase/2,2′-azino-bis(3-ethyl-benzothiazoline-6-sulfonic acid) is presented. The reaction proceeds under very mild conditions giving the product in quantitative yields. The enzyme requires at least one free ortho-position in the substrate molecule for the reaction to proceed.
