Study on Synthesis and Characterization of New 8- Trifluloromethyl Quinazolin-2,4-(3H)-Dione Nucleosides

The synthesis of 8-trifluloromethyl quinazolin-2,4-(1H,3H)-dione 2, which was ribosylated by coupling with 1-O-acetyl-2,3,5-tri-O-benzoyl—D-ribofuranose 4 via the silylation method, yielded mixture and -anomeric benzoylated nucleoside derivatives 5 and 6, respectively. As part of our ongoing interest in the synthesis of new nucleosides with expected biological activity, quinazolin-2,4-(3H)-dione nucleosides containing trifluloromethyl group were designed in this review.…
