A new series of bis‐heteroarylaminomethylnaphthoquinone Mannich bases have been synthesized through facial and efficient one‐pot pseudo five‐component reactions of lawsone, different heteroaryl amines and terephthaldehyde using p‐TSA as catalyst in CH3CN under reflux conditions. The high yields of products, very simple operation, readily available starting materials, high atom‐economy, easy workup procedure and isolation/purification of target products without chromatography are the main benefits of this synthetic strategy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
