摘要：

Fragmentations of a series of 2,2,4-trisubstituted 1,2-dihydroquinazolines were studied by electron impact (EI) ionization and positive- and negative-ion fast atom bombardment (FAB) coupled with collision-induced decomposition (CID). The El mass spectra give information that directly indicates the specific location of each substituent. The FAB-CID spectra provide data regarding the masses of each substituent, but no definitive information regarding location.
