bond formation by C–N bond cleavage on enaminones leading to the efficient synthesis of β-cyano enones is developed. The reactions take place efficiently to provide (E)-β-cyano enones with only a molecular iodine catalyst. In addition, the additional employment of oxalic acid enables the selective synthesis of (Z)-β-cyano enones.
开发了一种非常实用的方法,通过烯胺酮上的 C-N 键裂解形成 C-CN 键,从而有效合成 β-氰基烯酮。该反应有效地发生以仅用分子碘催化剂提供 ( E )-β-氰基烯酮。此外,额外使用草酸可以选择性合成 ( Z )-β-氰基烯酮。
