β¦ Synopsis
]pyridines (THPP) upon the reaction with DMAD in acetonitrile or DMSO at rt underwent ring expansion, affording tetrahydropyrrolo[2,3-d]azocines; these latter compounds have not previously been reported in the literature. The crystal structure and conformation of these derivatives was established by X-ray crystallography.

Reaction of pentaerythrityl tetrabromide with fluorenyl potassium gave the title compound in 53% yield. The crystal structure revealed that in this unique trispiro[4.1.1.4.1.1]pentadecatetraene derivative, the adjacent rings are planar and orthogonal.
