Summary
The main directions of fragmentation of 2,3-trimethylenetetrahydroquinazolines (I, II) and 2,3-trimethylenetetrahydroquinazolin-4-ones (III, IV) are the elimination of the C9-C10 chain with the subsequent splitting out of a methyleneimine radical and the elimination of the C9-C11 chain with the migration of hydrogen to the neutral (I, II) or the charged (III, IV) fragment.
