Abstract

Pyridin-3-ol reacted readily as 4 π electrocyclic component across the 2- and 6-positions of the pyridine ring with the potent azo-dipolarophile: 1,2,4-triazoline -3,5-dione. Structural and configuration assignments were deduced from elemental and spectral evidence. FMO treatment of the enhanced 1,3-dipolar character of pyridin-3-ol towards the cis-azo-dipolarophile was performed using ASED-MO calculations method.
