Abstract
- The new 5-arylmethylene-3-phenyl-4-thioxo-2-thiazolidinone derivatives have been synthesized by condensation ofω-(4-formylphenoxy)acetophenone derivatives with 3-phenyl-4-thioxo-2-thiazolidinone, in good yields. The cycloaddition of the newly synthesized compounds toN-arylmaleimides, ethyl acrylate andω-nitrostyrene has been studied. Under thermal reaction conditions [4+2] cycloaddition proceeds with complete site- and regioselectivity to yield the new fused thiopyrano[2,3-d]thiazole derivatives. [ABSTRACT FROM AUTHOR]
