摘要：

Protonation of the highly reactive 1:1 intermediates produced in the reaction between triphenylphosphine and dialkyl acetylenedicarboxylates by 2-hydroxyketones leads to vinylcriphenylphosphonium salts, which undergo an intramolecular Wittig reaction to produce functionalized dialkyl 2,5-dihydrofuran-2,3-dicarboxylates in fairly high yields.
