Abstract
The article describes the result of our study on rearrangements of four heterocyclic systems with variation of oxygen and nitrogen atoms, in particular, the results of formylation of 2,2-disubstituted hydroquinazolones under the conditions of the Vilsmeier-Haack reaction. A new rearrangement of spiro derivatives of quinazolin-4(3H)-ones was discovered under the action of a formylating reagent with the formation of predicted 1-cyclohex(pent)-1-en-1-ylchinazolin-4-(1H)-ones. The absence of this rearrangement for 2,2-dimethyl-2,3-dihydroquinazolin-4(1H)-one is explained. 6',7',7'-Trimethyl-1',5',6',7'-tetrahydrospiro [cyclohexane-1,2'-pyrrolo[3,4-d]pyrimidine]-4'(3'H)-one is a structural analogue of spiro derivatives of quinazolin-4(3H)-ones; it undergoes a similar rearrangement with the formation of 1-cyclopent-1-en-1-yl-6,7,7-trimethyl-1,5,6,7-tetrahydro-4H-pyrrolo[3,4-d]pyrimidin-4-one when interacting with Vilsmeier-Haack reagent.
