Laccase

Abstract

(A) Witayakran and Ragauskas reported a one-pot aqueous synthesis of 1,4-naphthoquinone in the presence of laccase. Equation Presented. enediamine into 2,3-diaminophenazine in 90% yield under mild conditions.Equation Presented.(C) Sc(OTf)3/SDS and laccase were used as recyclable catalysts to efficiently and directly synthesize benzofuran derivatives from the reaction of catechols and acetylacetone.Equation Presented.(D) Kidwai et al. have described the mild laccase-catalyzed synthesis of an HIV protease inhibitor, substituted benzopyranocoumarin, in 65% yield.Equation Presented.(E) Pilz et al. reported a convenient synthesis of a novel compound, 4-[2-(2-carboxyethyl)-4,5-dihydroxy- phenylamino]benzoic acid, by laccase-catalyzed cross-coupling in 80% yield.11Equation Presented.(F) Proteins containing large amounts of lysine residues can react with dihydroxylated aromatics to form a three-dimensional network through oxidative cross-links in the presence of laccase.
