Abstract: A new synthesis of twelve-, fifteen-, and eighteen-membered benzoazacrown ethers using palladium-catalyzed intramolecular amination is reported. Couplings proceeded in good yields using an in situ generated Pd(0) catalyst associated to N,N-bis(2,6-diisopropylphenyl)dihydroimidazol-2-ylidene (SIPr) as ligand and t-BuONa as the base.
