The reaction of 2-amino-2-oxazolines with ethoxycarbonyl isocyanate was investigated in order to access to fused 1,3,5-triazine-2,4-diones with a potential 5-HT2 antagonist activity. The reaction leads to 2,3,6,7-tetrahydro-4H-oxazolo[3,2-a]-1,3,5-triazine-2,4-diones and to 1-carbethoxy-3-(2-iminooxazoli-dine)ureas. During the carbamoylation the regioselectivity seems to be related to the strong nucleophilic character of the endo nitrogen atom of 2-amino-2-oxazolines. The structures of two compounds were studied by X-ray crystallography. N-Substituted compounds have been prepared by alkylation of the 2,3,6,7-tetrahydro-7-phenoxymethyl-4H-oxazolo[3,2-a]-1,3,5-triazine-2,4-dione.
