Abstract
Pyridin-3-ol reacts extremely fast as 4 pi electrocyclic component acr oss the 2- and 6-positions of the pyridine ring with the potent azo-di polarophile, 1, 2, 4-triazoline-3, 5-dione. Structural and configurati onal assignments are deduced from elemental and spectral evidence. FMO treatment of the enhanced 1, 3-dipolar character of pyridin-3-ol towa rds the cis-azo-dipolarophile has been performed using ASEDMO calculat ions method.
