【 摘 要 】

Dimedone reacted with aromatic aldehydes and 3,4-methylenedioxyphenol or β-naphthol in the presence of a catalytic amount of Preyssler type heteropolyacid, H₁₄[NaP₅W₃₀O₁₁₀], as a green and reusable catalyst under solvent-free conditions to form a variety ofnew xanthene derivatives in very goodyields.
