Rh2(II)-Catalyzed Nitro-Group Migration Reactions: Selective Synthesis of 3-Nitroindoles from β-Nitro Styryl Azides
摘要:
Rhodium carboxylate complexes (1 mol %) catalyze the migration of electron-withdrawing groups to selectively produce 3-substituted indoles from beta-substituted styryl azides. The relative order of migratorial aptitude for this transformation is ester << amide < H < sulfonyl < benzoyl << nitro.
