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