l-Proline-Catalyzed Three-Component Reaction of 4-Chloro-3-formylcoumarin, Sodium Sulfide, and α-Halo Ketones: A Direct Approach to Thieno[3,2- c ]coumarins
Thotathil, Vandana; Al-Zoubi, Raed M.; Sawali, Mona; Su, Haw Lih; Shkoor, Mohanad ( Georg Thieme Verlag KG , 2023 , Other)A new protocol for the synthesis of thieno[3,2-c]coumarins is disclosed. In this method, a 3-formyl-2-oxo-2H-chromene-4-thiolate anion is generated in situ by treatment of 4-chloro-3-formylcoumarin with sodium sulfide. ... -
