Abstract


The cyclocondensation of N-methylurea with derivatives of tetrahydroimidazooxazolone, tetrahydro-imidazooxazinone, dihydroimidazooxazinone, and tetrahydroimidazooxazepinone was studied for the first time. It was shown that the reactions take place with high regioselectivity, are regular in character, and lead to the formation of previously inaccessible 1,5-diaryl-2-(hydroxyalkyl)-8‑methylglycolurils with high yields.
