2. A visible light-initiated, one-pot, multi-component synthesis of 2-amino-4-(5-hydroxy-3-methyl-1 H-pyrazol-4-yl)-4 H-chromene-3-carbonitrile derivatives under solvent- and catalyst-free conditions.

Abstract

The reported work allows an accessible construction of 4-substituted 2-amino-4 H-chromenes starting from ethylacetoacetate ( 1), hydrazine hydrate ( 2), salicylaldehyde ( 3) and malononitrile ( 4) in the presence of visible light. The salient features of the proposed route is being a solvent-free and catalyst-free, one-pot, multi-component reaction with high to excellent yield. Visible light mediation makes the reaction mechanistically interesting and adds to the green credentials of the reaction. Graphical Abstract: [ABSTRACT FROM AUTHOR]
