Synthesis of Benzannulated N-Heterocycles by a Palladium-Catalyzed C−C/C−N Coupling of Bromoalkylamines
摘要:
A palladium-catalyzed domino intermolecular alkylation/intramolecular amination of functionalized aryl iodides represents a new strategy for the synthesis of benzannulated N-heterocycles, affording functionalized indolines and tetrahydroquinolines from simple precursors.

A novel method for the synthesis of β-amino alcohols has been demonstrated under mild reaction conditions with a broad scope via a two-step Smiles rearrangement. What is more, theoretical calculations have been performed to confirm the rationality of the mechanism. The method has been proved to be notably effective for N-arylated amino alcohols, which are difficult to synthesize by traditional methods
