N2 - 1,3‐Dipolar cycloadditions of stable 4‐azido‐6‐methyl‐2H‐pyran‐2‐one 1 with electron‐rich alkenes and alkynes lead to 4,5‐substituted 1‐(6‐methyl‐2‐oxopyran‐4‐yl)‐1,2,3‐triazoles. Iminophosphoranes derived from 1 have also been synthesized. 5‐Oxopyrano[4,3‐b]pyridines are prepared by reaction of 4‐amino‐6‐methyl‐2H‐pyran‐2‐one 2 with β‐dicarbonyl compounds.
