Abstract: | Thesynthesisof2-amino-5,5-dimethyl-3-cyano-4,5-dihydro-7H-furo2,3-c]pyrananditspyrroleanalog was accomplished on the basis of 2,2-dimethyltetrahydro-4-pyranone. Their reaction with maleic anhydride, which leads to the formation of 3-amino-4-cyano-6,6-dimethyl-5,6-dihydro-8H-pyranoc]-phthalic anhydride, was studied.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 3, pp. 316–318, March, 1991. |
