The total synthesis of enhygrolide A, a γ-alkylidene butenolide natural product which exhibits antibacterial activities, is reported. The synthetic route features several key transformations, including a copper mediated Sonogashira/oxacyclization 5-exo-dig process to generate the alkylidene butenolide system and a Suzuki cross-coupling to introduce the benzylic unit. The methodology employed for this total synthesis represents a sufficiently flexible route to allow the synthesis of numerous analogs of these enhygrolides.

We describe the synthesis of ionic-liquid-supported 1,3-dimethylimidazolidin-2-one, together with the halogenation of alcohols in a reaction system in which this reagent is combined with oxalyl chloride. A new method was established that does not require additives such as bases, and which permits the ready isolation and purification of the product. Good conversions were obtained, and good reusability of the reagent was observed.
