The manuscript describes a novel and efficient protocol for the synthesis of hexahydroazoninoindoles, based on the tandem cleavage–cyclisation reaction of hexahydroazepinoindoles with activated alkynes.

A reaction of substituted hexahydroazepino[4,3-b]-and-[3,4-b]indoles with activated alkynes was studied. A one-step method for the synthesis of isomeric hexahydroazonino[5,6-b]indoles different by positions of the double bond in the azonine ring was developed.
