chemo‐enzymatic aerobic oxidation in water of benzylamines to obtain aldehydes or imines is described. Laccase from Trametes versicolor was chosen as biocatalyst, and TEMPO (radical 2,2,6,6‐tetramethylpiperidine 1‐oxyl) as mediator. A study on the pH dependence of the aqueous medium allowed us to realise a fine tuning on product selectivity. Under our optimized reaction conditions, the bio‐oxidation
描述了一种在水中苄胺的有效,实用的化学酶促好氧氧化反应,以得到醛或亚胺。选择来自Trametes versicolor的漆酶作为生物催化剂,并以TEMPO(自由基的2,2,6,6-四甲基哌啶1-氧基)为介质。对水性介质的pH依赖性的研究使我们能够实现对产物选择性的微调。在我们优化的反应条件下,已实现了一系列伯,仲和环状胺的生物氧化。
