A biomimetic alcohol dehydrogenase (ADH)-like oxidation protocol was developed using an ortho-naphthoquinone catalyst in the presence of a catalytic amount of base. The developed organocatalytic aerobic oxidation protocol proceeds through the intramolecular 1,5-hydrogen atom transfer of naphthalene alkoxide intermediates, a mechanistically distinctive feature from the previous alcohol dehydrogenase
在催化量的碱存在下,使用邻萘醌催化剂开发了仿生醇脱氢酶 (ADH) 样氧化方案。开发的有机催化有氧氧化方案通过萘烷氧化物中间体的分子内 1,5-氢原子转移进行,这是与以前的醇脱氢酶模拟物不同的机械特征,该模拟物需要催化剂活性形式的金属。类似 ADH 的有氧氧化方案应该为现有的化学计量和金属催化的醇氧化反应提供绿色替代方案。
