A novel electrooxidative tandem cyclization method for the synthesis of 3-arylthiochromone derivatives is reported in this study. The reaction eliminates the need for metal catalysts, oxidants, and high reaction temperatures, and exhibits a wider scope of substrate tolerance, providing a new and efficient route to prepare 3-substituted chromones at room temperature.
A novel and electrooxidative tandem cyclization of enaminones with aryl/alkylthiol and ArSSAr to 3-arylthiochromone derivatives were reported. Compared to previous methods, the reaction doesn't need metal catalyst, oxidant and high reaction temperatures and it has a wider range scope of substrate tolerance. The reaction is environmentally friendly, providing a new and efficient route to make 3 -substituted chromones at room temperature.(c) 2022 Elsevier Ltd. All rights reserved.
