Synthesis of Benzothiophene-Fused Pyran Derivatives via Piperidine Promoted Domino Reaction

الملخص EN

A new domino reaction between thioaurones and malononitrile has been reported.

This reaction allows efficient access to benzothiophene-fused pyran derivatives in good yields under mild reaction conditions.

The substrate scope is broad; a series of benzothiophene-fused pyran derivatives have been synthesized.
