A copper-catalyzed Sonogashira coupling reaction and 5-exo-dig aminocyclization between 2-(2-bromophenyl)benzofuro[3,2-d]pyrimidin-4(3H)-ones and terminal alkynes were disclosed. The protocol allowed access to a series of 8-benzylidene benzofuro[3',2':4,5]pyrimido[2,1-a]isoindol-6(8H)-one derivatives with high efficiency, broad substrate scope, and excellent functional group compatibility, which were shown to be of a single (E)-configuration by X-ray diffraction analysis.

Key words: Benzofuropyrimidoisoindole, Sonogashira coupling, Acetylene hydroamination, CuI
