  Pd-Catalyzed Semmler–Wolff Reactions for the Conversion of Substituted Cyclohexenone Oximes to Primary Anilines

  摘要：

  Homogeneous Pd catalysts have been identified for the conversion of cyclohexenone and tetralone O-pivaloyl oximes to the corresponding primary anilines and 1-aminonaphthalenes. This method is inspired by the Semmler-Wolff reaction, a classic method that exhibits limited synthetic utility owing to its forcing conditions, narrow scope, and low product yields. The oxime N-O bond undergoes oxidative addition to Pd-0(PCy3)(2), and the product of this step has been characterized by X-ray crystallography and shown to undergo dehydrogenation to afford the aniline product.

  palladium‐catalyzed cascade reaction has been realized for the synthesis of 5H‐pyrrolo[2,3‐b]pyrazines and 5H‐pyrazino[2,3‐b]indoles from benzyl isocyanide by choosing o‐pivaloyloximes or o‐iodoanilines as a suitable substrate. The key steps involved are (i) oxidative addition of palladium through N–O or C–I cleavage; (ii) migratory double isocyanide insertion; and (iii) cross‐dehydrogenative coupling. Notable

  通过选择邻-吡咯并酮肟或邻-碘苯胺，已实现了钯催化的级联反应，可从异氰酸苄酯合成5 H-吡咯并[2,3- b ]吡嗪和5 H-吡嗪并[2,3- b ]吲哚。作为合适的基材。涉及的关键步骤是（i）通过N-O或C-I裂解氧化钯的加成；（ii）迁移性双异氰酸酯插入；（iii）交叉脱氢偶联。显着的特征是良好的官能团耐受性以及三个C–C和一个C–N键的形成。
