A convenient synthesis of methyl 1-alkoxy-3-perfluoroalkyl-2-naphthoates

Methyl 1-alkoxy-3-perfluoroalkyl-2-naphthoates 5 were synthesized by heating appropriately substituted 2-triphenylphosphoranylidene-2-butenoates 3 in xylenes at 250°C in a sealed tube. Compounds 3 were obtained via an intramolecular Wittig reaction of 2-alkoxycarbonylbenzyltriphenylphosphonium bromide (1) with methyl 2-perfluoroalkynoates 2 in the presence of potassium carbonate.
