Abstract
Ultraviolet irradiation of the triazolines (18a,b) formed by the high-pressure
addition of benzyl azide to dimethyl
3,6-di(2-pyridyl)-4,5-diazatetracyclo[6.4.1.0 2,3
.0 9,12
]trideca-3,5,7,10-tetraene-10,12-dicarboxylate (16a) and the related
monoester (16b), forms 13–17% of the expected aziridine (19a,b),
together with cyclobutane-cleavage products that include the hitherto unknown
pyridazinonorbornadiene (2), its di-π-methane rearrangement product (21)
and the corresponding triazoles (20a,b). Mechanistic pathways are discussed.
