Gein, O. Bobrovskaya, I. Kovtonogova, G. Gartman] Reaction of 3,4-diaryl-5-(4-guanidylsulfonylphenyl)-4,6-dihydropyrrolo[3,4-c]pyrazol-6-ones with ninhydrin in ethanol led to the formation of 5-[N-(4,10-dihydroxy-5-oxo-1,3-dihydrobenzocyclopentano[1,2-b]-2-imidazolidene)aminosulfonylphenyl]-3,4-diaryl-4,6-dihydropyrrolo[3,4-c]pyrazol-6-ones. Their structure was proved by IR and 1H NMR spectroscopy. Pleiades Publishing, Ltd., 2015 Gein V. Perm State Pharmaceutical Academy, Polevaya ul. 2, 614990, Perm, Russia aut Bobrovskaya O.
