## Abstract The regioβ and stereoselective construction of the azocino[__cd__]indole core was achieved by applying a Pdβcatalyzed intramolecular acetylene hydroarylation protocol. The applicability of a similar strategy for the synthesis of the azepino[__b__]indole framework is demonstrated.
Various pyrimido[4,5-b] indoles and benzo [4,5]furo [2,3-d]pyrimidines were synthesized via a palladium-catalyzed intramolecular arylation of pyrimidine substrates. Thus, 4-aryloxy-or 4-anilino-5-iodopyrimidines were treated with Pd(OAc) 2 (PPh 3 ) 2 and base in DMF to give the regioselective cycli
