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.

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