Abstract
Epoxydiazocines belong to the rare class of small V-shaped molecules, closely related
to Tröger’s base. Due to their intriguing, unique structure, they could serve as molecular
building blocks for supramolecular chemistry. An extensive review on their synthesis
is contained in this article. Moreover, our recent findings devoted to efficient and
easily scalable synthesis of fluorinated epoxy[1,5][b,f]diazocines through solvent-free base-catalyzed condensation of ortho-aminophenones is provided. The unique V-shaped structure was confirmed by X-ray crystal
structure analysis. Furthermore, the rigidity of the epoxydiazocine skeleton allowed
for racemate separation and the configuration of enantiomers was established by combining
quantum chemical calculations and chiroptical methods.
