title: [Synthesis and antimetabolite properties of 5-substituted 2'-deoxyuridines. Anomeric 5-(2-aminohexafluoroprop-2-yl)- and 5-(2-trifluoroacetylaminohexafluoroprop-2-yl)-2'-deoxyuridine].
abstract: Alkylation of 2,4-bis-O-(trimethylsilyl)uracil with hexafluoroacetone trifluoroacetylimine gave 5-(2-trifluoroacelylaminohexafluoroprop-2-yl)uracil, which was transformed by alkaline hydrolysis to 5-(2-aminohexafluoroprop-2-yl)uracil. The latter was glycosytated with 2-deoxy-3,5-di-O-p-toluoyl-alpha-D-ribofyranosyl chloride by means of various modifications of the silyl method leading to the predominant formation of beta-deoxynucleoside; after deacylation 1-(2-deoxy-beta-D-ribofuranosyl)-5-(2-aminohexafluoroprop-2-yl)ura cil was obtained. Interaction of silylated 5-(2-trifluoroacetylaminohexafluoroprop-2-yl)uracil with acylgalogenose gave anomeric O-substitutet deoxynucleosides, which were deblocked to give 5-(2-trifluoroacetylaminohexafluoroprop-2-yl)-2'-deoxyuridine and corresponding alpha-anomer. Alkaline hydrolysis of N-trifluoroacetyl group in both individual anomers produced 1-(2-deoxy-alpha-D-ribofuranosyl)-5-(2-aminohexafluoroprop-2-yl)ur acil and the abovementioned beta-anomer. Of all compounds synthesised only 1-(2-deoxy-beta-D-ribofuranosyl)-5-(2-aminohexafluoroprop-2-yl)ura cil has a moderate inhibitory effect on replication of vaccinia virus in vitro.
