Pent-4-yonic acid, in various alcohols, was cyclised in the presence of yellow mercury(II) oxide to 4,5-dihydro-5-alkoxy-5-methylfuran-2(3H)-ones; 8-hydroxyoct-4-yonic acid was also cyclised in dimethylformamide to 1,6-dioxaspiro[4.5]decan-2-one in good yield.
在黄色醇(II)氧化物存在下,将五元醇中的戊-4-磺酸酸环化为4,5-二氢-5-烷氧基-5-甲基呋喃-2(3 H)-酮;还以高收率将8-羟基辛基-4-磺酸在二甲基甲酰胺中环化为1,6-二氧杂螺[4.5]癸-2-。
