โœฆ Synopsis

3-Chloropentane-2,4-dione exists, in solution, almost exclusively as enol tautomer, which undergoes a complex reaction with dialkyi acetylenedicarboxylates and triphenylphasphine to produce alkyl 5,3-diacetyl-2-oxo-3-(triphenyiphosphoranylidene)tetrahydrofuran-4-carboxylates in moderate to fairly high yields.

Vinyltriphenylphosphonium Salt Mediated One-Pot Synthesis of Functionalized 3-(Triphenylphosphoranylidene)butyrolactones. -Dialkylacetylenedicarboxylates react with triphenylphosphine and 3chloropentane-2,4-dione in its enol form (II) to produce the hitherto unknown tetrahydrofuranones (IV), which
