| Abstract: |
Three-component cyclization of ethyl 4,4,4-trifluoroacetoacetate and cycloheptanone with 1,2-diamines, 1,3-diamines, and 1,2-aminoalcohols leads to previously unknown types of tricyclic azaheterocyclic structures, which are trifluoromethyl-substituted cyclo-hepta-annulated derivatives of imidazo[1,2-a]-, oxazolo[3,2-a]pyridin-5-ones, pyrido[1,2-a]-pyrimidin-6-one, and pyrido[2,1-b]quinazolin-8-one. The structure of these diastereomeric heterocycles was established, and the mechanism of their formation was proposed. [ABSTRACT FROM AUTHOR] |
