A versatile method for the synthesis of novel brominated 4-alkyl-2(5H)-furanones under mild reaction conditions is described. This synthetic strategy requires only one chromatographic separation over six steps and employs the cyclodehydration of brominate
Butenolide Syntheses, II. Simple Synthesis of 4-Substituted 2,2-Diethoxy-5-alkylidene-2,5-dihydrofurans, 3-Substituted 4-Alkylidene-2-butene-4-olides or 5,6-Dihydro-2-pyrones

Reaction of the (2,2-diethoxyvinylidene)triphenylphosphorane (5) with enolizing 1,2-diketones 3 via the (2,2-diethoxyvinyl)triphenylphosphonium enolates 6 yields the orthoesterphosphoranes 7, which in an intermolecular Wittig reaction spontaneously give t
