Treatment of monoalkylsubstituted allenic esters 4 with NBS and water in the darkness yields β-bromo-α,β-butenolides 5, that are easily transformed into 5-alkyl-4-bromo-5-hydroxy-2(5H)-furanones 8 and 5-alkylidene-4-bromo-2-(5H)-furanones 2.
Easy Access to 5-Alkyl-4-bromo-2(5H)-furanonens: Synthesis of a Fimbrolide, an Acetoxyfimbrolide, and Bromobeckerelide

Treatment of γ-monosubstituted allenic esters with N-bromosuccinimide in water yields 5-alkyl-4-bromo-2(5H)-furanones, that can be transformed into 4-alkylidene-4-bromo-2(5H)-furanones in good overall yields.Starting with a simple allenic ester these tran
