Abstract

Abstract Reactions of 5-amino-1, 3-dialkyl-1, 3-dihydrobenzimidazol-2-ones with 2, 5- dimethoxytetrahydrofuran and 2, 6-dimethyl-γ-pyranone led to the formation of 1, 3-dialkyl-1, 3-dihydro-5-(pyrrol-1-andл) benzimidazol-2-ones and 1-(1, 3-dialkyl-2-oxo-1, 3- dihydrobenzimidazol-5-yl)-2, 6-dimethylpyridin-4-ones.
