Exothermic or endothermic? This question arises for some intramolecular 1,3‐dipolar cycloaddition reactions of azides. The picture schematically illustrates the answer for alkene and aldehyde units as dipolarophiles. In their Full Paper on page 5539 ff. , S. Firdous, K. Banert, and A. A. Auer used both experimentally and quantum chemical methods to investigate the possibility of generating known and supposedly known nitrogen heterocycles.
