Modular Synthesis of Di‐ and Triazadibenzoazulenes by a Cross‐Coupling/Cycloisomerization Strategy

Imidazo[1,2‐ a ]pyridines and imidazo[1,2‐ a ]pyrazines are important nitrogen‐containing heterocycles with applications in medicinal and materials chemistry. Herein, we report a regioselective synthetic strategy for the preparation of novel diaza‐ and triazadibenzoazulene derivatives through sequential Pd‐cataly...
