-TSA-Based DESs as “Active Green Solvents” for Microwave Enhanced Cyclization of 2-Alkynyl-(hetero)-arylcarboxylates: an Alternative Access to 6-Substituted 3,4-Fused 2-Pyranones
An acidic Deep Eutectic Solvent is an alternative environmental‐friendly “active” media for the microwave‐mediated synthesis of 6‐substituted 3,4‐fused 2‐pyranones.
