The reactions of partially hydrogenated indole-fused quinolizines and indolizines with activated alkynes in methanol, acetonitrile, and dichloromethane were studied. The reactions were shown to be accompanied by the cleavage of the bridging C-N bond. Azecino[5,4-b]-indole and indolo[3,2-e][2]benzazonine derivatives were synthesized.
