Synthesis of 1,3-Dienes from Alkenes via Alkenyl Thianthrenium Salts

Key Points

• The research aims to develop a new method for synthesizing 1,3-dienes from alkenes using thianthrenium salts.
• Used C-H thianthrenation to convert alkenes to alkenyl thianthrenium salts.
• Conducted a Pd-catalyzed three-component coupling reaction with allene gas and nucleophiles.
• Demonstrated the modularity and robustness of the method for synthesizing complex 1,3-dienes.
• Successfully converted a variety of alkenes into alkenyl thianthrenium salts.
• Achieved high yields of structurally complex 1,3-dienes through the coupling reaction.
• Showed that the method allows access to compounds difficult to synthesize by traditional means.
