The racemate of 2,5-dihydro-3-hydroxymethyl-2,5-dimethoxy-2-methylfuran (11), prepared from the reaction of 3-hydroxymethyl-2-methylfuran (12b), with bromine in methanol, is converted into the racemate of 4-hydroxy-2-hydroxymethylcyclopent-2-en-1-one (9a) when heated in aqueous dioxan buffered at pH 6.3.
由3-羟甲基-2-甲基呋喃(12b)与溴在甲醇中的反应制得的2,5-二氢-3-羟甲基-2,5-二甲氧基-2-甲基呋喃的外消旋体转化为在pH 6.3缓冲的二恶烷水溶液中加热时,4-羟基-2-羟甲基环戊-2-烯-1-酮(9a)的外消旋体。
