Synthesis of New Heterocycles from Reactions of 1‐Phenyl‐1 H ‐pyrazolo[3,4‐ b ]pyridine‐5‐carbonyl Azides

Synthesis of New Heterocycles from Reactions of 1‐Phenyl‐1 H ‐pyrazolo[3,4‐ b ]pyridine‐5‐carbonyl Azides

Two individual examples of pyrazolo[3,4‐ b ]pyridine‐5‐carbonyl azides and hydrazides were reacted with various nucleophilic reagents. Different unexpected behaviors was observed. NMR, IR, mass spectra together with elemental analyses and X‐ray structure analyses, were used to prove the structure of...
