Base-Promoted Cascade Multicomponent Access to Azatrithiathiophthenes from Cinnamonitriles, Sulfur and Active Methylhetarenes

Key Points

• To develop a novel method for synthesizing azatrithiathiophthene heterocycles using diverse reactants.
• Utilized multiple C-H functionalization techniques
• Involved active methyl hetarenes and cinnamonitriles
• Incorporated elemental sulfur in the reaction
• Produced a series of novel azatrithiathiophthenes
• Introduced a tetravalent sulfur atom linking two fused heterocycles
• Demonstrated the effectiveness of the multicomponent reaction strategy
