摘要：

Silica-supported phosphomolybdic acid was found to be an efficient heterogeneous catalyst for the synthesis of 1.8-dioxooctahydroxanthenes from aldehydes and dimedone and of tetrahydrochromenes from the same reaction mixture along with malononitrile. The products were formed in excellent yields. The catalyst can be recovered and reused.
