(or α-bromomethylacrylic acid) can be carried out under mild condition, the products 4-hydroxy-2-methylenebutanoates (or 4-hydroxy-2-methylenebutanoic acids) can be easily converted to α-methylene-γ-butyrolactones in the presence of CF3COOH.
摘要 在铅粉存在下,醛类与α-溴甲基丙烯酸酯(或α-溴甲基丙烯酸)反应可在温和条件下进行,产物4-羟基-2-亚甲基丁酸酯(或4-羟基-2-亚甲基丁酸) ) 在 CF3COOH 存在下可以很容易地转化为 α-亚甲基-γ-丁内酯。
