The benzoyl peroxide-catalyzed reaction of 2-bromoalkanoic acids such as bromoacetic, 2-bromopropionic, and 2-bromobutyric acid with 1-alkenes was found to proceed through the addition of the C–Br bond across the double bond followed by cyclization affording 4-alkanolides in good yields.
Benzoyl peroxide-catalyzed freeradicaladdition of bromoacetic, α-bromopropionic, and α-bromobutyric acids to olefins took place under mild conditions to afford γ-alkyl-, γ-alkyl-α-methyl-, and γ-alkyl-α-ethyl-γ-butyrolactones in good yields.
