Abstract

Catalytic [6π+2π]-cycloaddition of terminal alkynes to N -carbofluorenylmethoxyazepine under the action of a three-component catalytic system Co(acac)2(dppe)/Zn/ZnI2 was performed for the first time to obtain previously undescribed and promising 9-azabicyclo[4.2.1]nona-2,4,7-trienes (in 79-92% yields) containing a fluorene substituent.
