Efficient and Practical Protocol for the Synthesis of Pyridopyrazines, Pyrazines and Quinoxalines Catalyzed by La(OAc)3 in Water

Abstract

La(OAc)3 has been used as an efficient catalytic system for the synthesis of quinoxalines. This method provides several advantages over methods that are currently employed such as a simple work-up, mild reaction conditions, good to excellent yields, and a process to recover and reuse the catalyst for five cycles with consistent activity.
