Abstract
The thermolysis of tert-butylperpent-4-enoate in various solvents ZH (carboxylic acids, anhydrides, methyl esters, nitriles) led to γ-butyrolactones 4-substituted by the group ZCH2 with good yields. The acidic treatment of the lactones 4 and 6 derived from non-functionalized alkanoic acids and methyl esters gave respectively the isomerized lactones 5 and 7, increasing the synthetic interest of the studied homolytic reaction.Keywords
