Indoles Synthesized from Amines via Copper Catalysis
摘要:
N-Substituted indoles are synthesized from primary amines through a tandem reaction sequence. Initial condensation of the amine with an alpha-(o-haloaryl)ketone or aldehyde is followed by intramolecular aryl amination catalyzed by CuI. A variety of anilines and alkyl amines, including those with significant steric demands, are converted to indoles in high yields and with varying indole substitution.

Selective base‐Mediated hydroamination of N‐heterocycles with olefins for the construction of Linear and branched N‐alkylated heterocycles is described. This protocol provided the synthesis of exclusive N‐alkylated product instead of the C‐3 Michael addition product.
