RESUMO
Phosphoryl chloride was able to promote the formation of peptide and the ringopening of tetrahydrofuran (THF) followed by a sequence of successive reactions by simply refluxing. ESI multistage tandem mass spectrometry was applied to trace the reaction and elucidate the product structures, dipeptide 4-chlorobutyl ester.

RESUMO
Phosphorus oxychloride was found to induce ring opening of tetrahydrofuran (THF) to synthesise THF oligomer incorporated phosphate. ESI multi-stage tandem mass spectrometry was used to study the products and confirm the structures.
