Synthesis and spatial structure of 3,7-dihydroxy-7-(trifluoromethyl)hexahydropyrrolo[1,2-a]pyrimidines
A characteristic feature of the three-component cyclization of ethyl trifluoropyruvate and methyl ketones with 1,3-diamino-2-propanol is the formation of 8a-alkyl(phenyl)-3,7-dihydroxy-7-(trifluoromethyl)hexahydropyrrolo[1,2-a]pyrimidin-6(2H)-ones as one, two, or three diastereomers, depending on the methyl ketone component. The structures of the new heterocycles were established using the data of X-ray diffraction and 1H and 13C NMR spectra, including 2D 1H—13C HSQC, HMBC, 1H—1H COSY, and NOESY experiments.
