Enolates of acyl phosphoranylidine carboxylates react with aldehydes to form secondary alcohols which undergo intramolecular addition to the central carbonyl of a vicinal tricarbonyl unit, generated in a separate step. The resulting dihydrofuranols undergo acid-catalyzed dehydration to form 3-hydroxyfuran-2-carboxylates.
酰基磷酰基yl烷羧酸酯的烯醇酸酯与醛反应形成仲醇,该仲醇分子内加成到邻位三羰基单元的中心羰基上,在一个单独的步骤中生成。所得的二氢呋喃醇经过酸催化的脱水以形成3-羟基呋喃-2-羧酸酯。
