Synthesis of Acrylonitrile Derivatives via Visible Light‐induced Coupling Reaction of Morita‐Baylis‐Hillman Adducts with Tertiary Amines and α‐Trimethylsilyl Amines

Ru‐catalyzed coupling reaction of Morita‐Baylis‐Hillman (MBH) adducts with tertiary amines and α‐trimethylsilyl amines under visible light is disclosed. Compared with the reported MBH adducts with ester as withdrawing‐electron groups, MBH adducts with cyano group in this paper show different chemical reaction characteristics. The universality of substrates has been extended. A series of structurally complementary acrylonitriles are obtained in satisfied yields under mild condition, which provides a good opportunity to discover new meaningful bioactive compounds. The photoredox coupling of tertiary amines and α‐trimethylsilyl amines with Baylis‐Hillman adducts under visible light irritation was successfully established. The scope of the substrates was broad and an array of acrylonitriles derivatives was obtained in satisfied yields.
