由芳香醛和苄烯丙二腈出发, 发展了基于可见光诱导串联Giese加成-环化反应过程的4,5-二氢呋喃衍生物的合成新方法. 该反应无需过渡金属催化剂, 为构建多取代二氢呋喃衍生物提供了简便且立体选择性的制备路径, 是现有方法的重要补充.

A synthetic method for multi-substituted 4,5-dihydrofuran compounds through tandem Giese addition/cyclization process under visible light-induced photoredox catalysis from aromatic aldehydes and 2-benzylidenemalononitriles is reported. The reaction was carried out in the absence of transition metal catalysts, providing a simple and stereoselective approach for constructing multi-substituted 4,5-dihydrofurans and making it an important supplement to existing methods.
