New tricyclic compounds with pyrimido[4,5-d]pyrimidine fragment, the 7,8-dihydro-1H-pyrimido[4,5,6-de]quinazoline derivatives

A reaction of 2-diaminomethylidenedimedone with aryl isocyanates leads to the formation of the corresponding ureas, which upon the action of sodium methoxide cyclize to 4-amino-7,8-dihydroquinazoline-2,5(1H,6H)-dione derivatives. The latter react with aryl isocyanates following the similar scheme to furnish 1,6-diaryl-8,8-dimethyl-7,8-dihydro-1H-pyrimido-[4,5,6-de] quinazoline-2,5(3H,6H)-diones, new tricyclic compounds containing pyrimidopyrimidine fragment.
