  • Abstract Intramolecular criss-cross cycloaddition of 3-substituted symmetrical homoallenyl azines 2 by heating in xylene lead to interesting fused heterocyclic systems consisting of four five-membered rings with two nitrogen atoms in the skeleton 3. These compounds 3 were found to be sensitive to attack by alkyl halides. Their presence, depending on the reaction conditions, resulted in a new type of rearrangement leading to compounds 4 and 5, respectively. With an excess of alkyl halide and in… CONTINUE READING
