A method for the nucleophilic amination of methoxy arenes was established by using sodium hydride (NaH) in the presence of lithium iodide (LiI). This method offers an efficient route to benzannulated nitrogen heterocycles. Mechanistic studies showed that the reaction proceeds through an unusual concerted nucleophilic aromatic substitution.

(Chemical Equation Presented) Five 1-benzazepine heterocycles were synthesized by utilizing transition-metal-catalyzed processes in key bond-forming steps. exo-Methylene and methyl substituents were introduced at position 5, as well as a unit of unsaturat

A synthetic route to 1-benzyl-tetrahydro-1-benzazepine is reported, which also permits access to analogous structures with alkyl and aryl substituents at position-2 of the aliphatic ring. Palladium catalysis is utilized in two of the three steps, construc

(Matrix presented) The use of an in situ generated Ni(0) catalyst associated with 2,2′-bipyridine or N,N′ -bis(2,6-diisopropylphenyl)dihydroimidazol-2-ylidene (SIPr) as a ligand and NaO-t-Bu as the base for the intramolecular coupling of aryl chlorides with amines is described. The procedure has been applied to the formation of five-, six-, and seven-membered rings.
Intramolecular palladium-catalyzed aryl amination and aryl amidation
Wolfe, John P.,Rennels, Roger A.,Buchwald, Stephen L.
, p. 7525 - 7546 (2007/10/03)
Upon treatment with a palladium catalyst and a suitable base, aromatic halides undergo intramolecular substitution to form five, six, and seven-membered rings. In a similar fashion aryl halides with pendant amides or sulfonamides are cyclized to form five and six-membered rings.
