本文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制备路径,是现有方法的重要补充。

We report 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. 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.

Key words: dihydrofuran, visible light irradiation, Giese reaction, cyclization, aldehydes
