A mass spectrometric study of six new a-methylene-y-lactone carbohydrate derivatives has been carried out in order to correlate the occurrence of metastable transitions with the stereochemistry of the compounds. Results indicate that the decomposition of some metastable fragment ions usually release
The presence of an a-methylene-y-butyrolactone is essential for cytotoxic activity3 among the sesquiterpene lactones. Recently it has been established 3c,4 that the presence of a lipophilic, conjugated ester side chain located homoallylic to the exocyclic double bond of an a-methylene-ybutyrolactone
