Abstract For the first time, we have observed a combined effect of two bases NaOH/Et3N to promote the diazo transfer reaction of β-oximino esters. This unusual synergistic effect has been employed to obtain α-diazo oxime ethers directly from β-keto esters by one-pot process. This method is simple and cost-effective and the reagents are readily available. GRAPHICAL ABSTRACT
摘要 我们首次观察到两种碱NaOH/Et3N的联合作用促进β-肟基酯的重氮转移反应。这种不寻常的协同效应已被用于通过一锅法直接从 β-酮酯获得 α-重氮肟醚。该方法简单经济,试剂易得。图形概要
