An efficient one-pot synthesis of α, β-unsaturated esters through the aerobic oxidation – Wittig tandem reaction of alcohols and phosphorous ylide is developed. This new method operates under mild reaction conditions, and uses CuI/TEMPO (TEMPO = 2,2,6,6-tetramethylpiperidine-N-oxyl) as co-catalyst and air (O₂) as the oxidant. It tolerates a wide range of functionalized benzylic alcohol and aliphatic alcohols.

通过一锅铜催化的好氧氧化-Wittig反应轻松合成α，β-不饱和酯

开发了一种有效的一锅法合成α，β-不饱和酯的方法，即通过醇与磷的叶立德的好氧氧化-Wittig串联反应。该新方法在温和的反应条件下运行，并使用CuI / TEMPO（TEMPO = 2,2,6,6-四甲基哌啶-N-氧基）作为助催化剂，并使用空气（O ₂）作为氧化剂。它可以耐受各种官能化的苯甲醇和脂肪醇。
