Ethyl ylidenecyanoacetates undergo cyclization in cold sulfuric acid to give the lactone and o-aminoester . The key o-aminoester is used to the synthesis of a variety of as-hydrindacene derivatives including o-aminocarboxylic acid , o-hydroxyester , o-hydroxycarboxylic acid , or the ester .
亚乙基氰基乙酸乙酯在冷硫酸中进行环化反应,得到内酯和邻氨基酯。关键的邻氨基酯用于合成多种邻苯二氢并茂衍生物,包括邻氨基羧酸,邻羟基酯,邻羟基羧酸或酯。
