  Palladium(II)-catalyzed carbonylation of 3-buten-1-ols and 3-butyn-1-ols: an efficient synthesis of .gamma.-butyrolactones

  摘要：

  Palladium(II)-catalyzed dicarbonylation of 3-buten-1-ols (1) in the presence of propylene oxide and ethyl orthoacetate in methanol-dichloromethane under carbon monoxide at atmospheric pressure afforded alpha-[(methoxycarbonyl)methyl]-gamma-butyrolactones (2) in good yields. This dicarbonylation reaction occurs via stereospecific cis addition. Under similar conditions, 4-(trimethylsilyl)-3-butyn-1-ols (4a and 4b) undergo dicarbonylation to provide cis-dicarbonylated alpha-methylene-gamma-butyrolactones (5a and 5b, respectively). 4-Alkyl-and 4-aryl-3-butyn-1-ols (4c-g), on the other hand, undergo trans alkoxycarbonylation across the triple bond and selectively furnish E tetrasubstituted alpha-methylene-gamma-butyrolactones (6).

  Palladium-catalyzed mono- and bis(alkoxycarbonylation)s of olefins were controlled by the use of copper(II) and copper(1) chloride, respectively, in alcohol under normal pressure of carbon monoxide and oxygen at room temperature without any other additives. 3-Buten-1-ols gave the corresponding γ-butyrolactones and 2-oxotetrahydrofuran-3-acetic acid esters, respectively, in high yields.

  在室温下、正常压力的二氧化碳和氧气环境下，使用铜(II)和铜(I)氯化物分别控制钯催化的单和双(烷氧基羰基化)反应，无需其他添加剂即可使烯烃产生反应。3-丁烯-1-醇则分别高效地生成相应的γ-丁酰内酯和2-氧杂四氢呋喃-3-乙酸酯。
