Publikováno v: Il Farmaco. 58:69-77
The behaviour of di- and tri-fluorinated-ephedrines and -norephedrines has been studied by fast atom bombardment, atmospheric pressure chemical ionisation (APCI) and electrospray ionisation (ESI) experiments and compared with that of the unfluorinate

Is the atmospheric pressure chemical ionisation and collisionally induced methanol loss from protonated dehydroamino acids a retrosynthetic process?
Autor: Ana I. Jiménez, Michela Tubaro, Pietro Traldi, Carlos Cativiela, Maria Anna Fedrigo
Publikováno v: Rapid Communications in Mass Spectrometry. 17:107-113
Unsaturated 5(4H)-oxazolones lead, by methanolysis, to the corresponding dehydroamino acid derivatives. Interestingly, under atmospheric pressure chemical ionisation (APCI) conditions, the latter give rise, aside from abundant [M+H]+ ions, to [MHCH3O
