Solvent-Free Synthesis of 2-Amino-4H-Chromenes Catalyzed by Sodium Carbonate
Published: 16 November 2008 by MDPI in The 12th International Electronic Conference on Synthetic Organic Chemistry session General Organic Synthesis
Abstract: Solvent-free synthesis of substituted 2-amino-4H-chromenes is described using sodium carbonate as a green and reusable catalyst. The procedure is very simple, efficient and environmentally friendly as it does not use any toxic auxiliary or solvent.
