Diastereoselective Synthesis of Dibenzo[b,d]azepines by Pd(II)-Catalyzed [5 + 2] Annulation of o-Arylanilines with Dienes

An efficient method for the construction of dibenzo[b,d]azepines containing two distinct stereogenic elements in a highly diastereoselective fashion is described. The key of the [5 + 2] reaction is to form a π-allylpalladium species through sequential C-H

Pd-catalyzed sequential C-C and C-N bond formations for the synthesis of N-heterocycles: Exploiting protecting group-directed C-H activation under modified reaction conditions

Easy & efficient: A Pd-catalyzed domino olefination/conjugate addition reaction of N-Ts-2-arylanilines with activated olefins has been achieved at ambient temperature under the newly defined reaction conditions. This process highlighted the directing effect of the N-protecting group in C-H activation, displayed broad substrate scope with wide functional group compatibility; thus rendering a straightforward entry to a wide variety of N-heterocycles such as dihydrophenanthridines.

Synthetic Routes to Arylpyrido-azepines and -azepines.

9-Phenyl-6-methoxy-5H-pyridoazepine and 9-phenyl-7-methoxy-5H-pyridoazepine have been obtained by arylation (PhLi) of 6,9-dimethoxy-5H-pyridoazepine and by photolysis of 6-azido-9-phenylquinoline in potassium methoxide-methanol-dioxan

Oxidative Cyclizations. VII. Cyclization of 2-Substituted Anilines with Alkaline Hypohalite

The Green-Rowe oxidation of 2-nitroanilines with alkaline hypohlorite, to yield benzofuroxans, is demonstrated by studies of the visible spectra of transient intermediates to proceed through N-chlorination and a singlet nitrene.Two variations on the route to the nitrene are possible.The cyclization step is represented as an internal capture of the nitrene by the ortho substituent, and on this basis the Green-Rowe oxidative cyclization is now extended to anilines whose ortho substituent is benzoyl or phenylazo.It is not however successful for ortho phenyl.Azo compounds were observed as byproducts in some of these reactions, and are shown to arise via N,N-dichloroanilines.
