Efficient Synthesis of Heterocyle-Fused β-Naphthylamines via Intramolecular Addition to a Cyano Group Initiated by Nucleopalladation of Alkynes
摘要:
A palladium(II)-catalyzed efficient synthesis of heterocycle-fused beta-naphthylamines was accomplished via nucleophilic addition of a carbonpalladium bond to the intramolecular cyano group initiated by nucleopalladation (oxypalladation or aminopalladation) of alkynes.

study, we report the palladium(ii)-catalyzed regioselective ortho-C-H bromination/iodination of challenging arylacetamide derivatives using N-halosuccinimides as halogenating agents. Diverse arylacetamides underwent the regioselective ortho-bromination and iodination of aromatic C-H bonds in the presence of a reactive benzylic C(sp3)-H bond without installing any bulky auxiliaries via unfavorable six-membered

The synthesis of the highly strained 3-aza-[7]-paracyclophane core of haouarnines A and B is based on a macrocyclization-aromatization protocol, allowing for a stepwise increase in ring strain and establishing the oxygenation pattern of the natural products.
