Abstract: A green, efficient, and regioselective one‐pot three‐component synthesis of 3‐benzoyl‐4‐phenyl‐4 H ,5 H ‐thiopyrano [2,3‐ b ]chromen‐5‐one derivatives has been developed. This protocol utilizes 4‐hydroxy‐2 H ‐chromene‐2‐thione, aromatic aldehydes, and β ‐enaminones, mediated by triphenylphosphine… read more here.
