4-烷基汉斯酯是一种很好的烷基自由基储存体.研究了4-烷基汉斯酯和Baylis-Hillman加成物在光催化氧化还原条件下制备多取代的αβ-不饱和羧酸酯.该反应条件温和,无需额外添加剂,偶联产物收率中等到良好.

关键词: 可见光催化, 自由基加成, Baylis-Hillman加成物, 4-烷基汉斯酯

4-Alkyl Hasntzch esters are good alkyl radical storage. The preparation of multisubstituted α,β-unsaturated carboxylic acid esters under photocatalytic redox conditions by 4-alkyl Hantzsch esters and Baylis-Hillman adducts was investigated. The reaction conditions are mild and no additional additives are required. The coupling products were obtained in moderate to good yields.

Key words: visible light photocatalysis, radical addition, Baylis-Hillman adducts, 4-alkyl Hantzsch esters
