New 7-alkynyl-9-azabicyclo[4.2.1]nona-2,4,7-triene-9-carboxylates were obtained upon the Co(acac)2(dppe)/Zn/ZnI2-catalyzed [6p+2p]-cycloaddition of 1,3-diynes to ethyl/phenyl azepine-1-carboxylates. The structures of the obtained azacyclic compounds were established by 1D and 2D NMR spectroscopy. The compounds prepared were tested for antitumor activities in vitroagainst Jurkat, K562, U937 and HL60 cancer cell lines.
