Concurrent α-iodination and N-arylation of cyclic β-enaminones

A variety of N-substituted 3-aminocyclohex-2-enones were converted into the corresponding N-arylated α-iodo enaminones in high yields via concurrent N-iodination and N-arylation mediated by ArI(OAc)2. A mechanism is postulated to account for the reaction differences between the cyclic and the acyclic -enaminones, which undergo predominant β-acetoxylation under the same reaction conditions.

An improved method for the synthesis of carbazolones by palladium/copper-catalyzed intramolecular annulation of n -arylenaminones

An improved method for the synthesis of carbazolones via the condensation of arylamines with 1,3-cyclodiketones followed by intramolecular oxidative cyclization catalyzed by palladium acetate and copper acetate in ethanol under an oxygen atmosphere was established. The improved method has the advantage of easily available starting materials and affords good yields.
