The mass spectrometric behaviour of four 2,3-dihydro-1-benzofuran-3-acetic acids has been studied in detail with the aid of exact mass measurements, linked scans, collisionally activated decomposition, mass analysed ion kinetic energy spectra and labelling experiments.Unusual fragmentation pathways are emphasized for which mechanisms are proposed.
OXYGEN HETEROCYCLES BY SULPHUR YLIDE ANNULATION: 2,3-DIHYDRO-BENZOFURAN-3-ACETIC ACIDS FROM ortho-HYDROXYBENZALACETIC ACID METHYL ESTERS AND DIMETHYLSULPHOXONIUM METHYLIDE
