Microwave-Assisted, Metal-Free, Base-Mediated C–N Bond Formation/Cleavage: Synthesis of Benzimidazo[1,2-a]quinazoline Derivatives
文摘
A novel, rapid, and efficient microwave-assisted, metal-free, base-mediated approach has been developed for the construction of benzimidazo[1,2-a]quinazolines from readily available building blocks. This synthetic strategy affords a diverse range of benzimidazo[1,2-a]quinazoline derivatives in moderate to good yields.
