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

Abstract

<em>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.</em>
