L-Proline Catalyzed Solvent-Free Knoevenagel Condensation for the Synthesis of 3-Substituted Coumarins

L-Proline Catalyzed Solvent-Free Knoevenagel Condensation for the Synthesis of 3-Substituted Coumarins

L‐Proline was utilized as an efficient organo‐catalyst for the environmentally benign synthesis of 3‐substituted coumarins by the Knoevenagel condensation of substituted 2‐hydroxybenzaldehydes with reactive methylene compounds under solvent free conditions.
