FIELD: chemistry.
SUBSTANCE: invention relates to a method of obtaining novel 3-aroyl-3a-(3,4-dihydro-2H-pyrane-5-yl)-2-hydroxypyrrolo [1,2-a]quinoxaline-1,4(3aH,5H)-diones of formula I, which consists in fact that 3-aroylpyrrolo[1,2-α]quinoxaline-1,2,4(5H)-triones reacts with 3,4-dihydro-2H-pyrane in inert aprotic solvent, followed by extraction of target products.
EFFECT: these compounds can be used as initial products for synthesis of novel heterocyclic systems and in pharmacology.
