of 2-iodoacetamide and 5-hexen-1-ol in water at 75 °C in the presence of a water-soluble radical initiator, 4,4′-azobis(4-cyanopentanoic acid), provided γ-(4-hydroxybutyl)-γ-lactone in 95% yield. The use of 2-iodoacetic acid in place of 2-iodoacetamide also gave the same γ-lactone in 93 % yield.
在水溶性自由基引发剂4,4'-偶氮双(4-氰基戊酸)存在下于75°C在水中加热2-碘乙酰胺和5-hexen-1-ol的混合物,得到γ-(4 -羟基丁)-γ-内酯,产率为95%。用2-碘乙酸代替2-碘乙酰胺也以93%的产率得到了相同的γ-内酯。
