Abstract
Based upon previously discovered antileukemic properties of 9-beta-D-fucopyranosyladenine (1) in cell culture, four new nucleosides containing naturally occurring bases have been prepared from D-fucose. alpha-D-Fucopyranose tetraacetate was condensed with the silylated bases in either acetonitrile or 1,2-dichloroethane with tin(IV) chloride as the catalyst. The intermediate blocked nucleosides were obtained in crystalline form and deacetylated with methanolic sodium methoxide. 1-beta-D-Fucopyranosyluracil (8), 1-beta-D-fucopyranosylthymine (9), 1-beta-D-fucopyranosylcytosine (10) as the hydrochloride salt, and 7-beta-D-fucopyranosylguanine (11) were crystallized, and their structures were verified by spectroscopic techniques. Nucleosides 8 and 9 had only borderline activity against leukemia L1210 cells grown in culture, whereas nucleoside 11 had activity equal to 1. However, nucleoside 10 proved to be twice as active as either 1 or 11. The antileukemic activity, which was due to the inhibition of cell division, was reversible by transfer of the arrested cells to fresh media or by the addition of cytidine.

Abstract
The primary hydroxy group of ethyl 2,3-dideoxy-alpha-D-erythro-hex-2-enopyranoside (1) was selectively protected and the secondary hydroxy group was deoxygenated via the dithiocarbonate 3 from which ethyl 6-O-(4-methoxybenzoyl)-2,3,4-trideoxy-alpha-D-glycero-hex-2-eno pyranoside (4) and its regioisomer (5) were produced. These were converted into didehydro nucleosides by glycosylation of silylated heterocyclic bases in the presence of trimethylsilyl trifluoromethanesulfonate as catalyst. The configurations of the anomeric products were assigned by 1H-NMR analysis of the corresponding saturated compounds which were obtained by hydrogenation of the double bond in the carbohydrate moiety. The compounds 9a,b,d, 10a,b, 14a,b,e,f, and 15a,b,e,f did not show any significant activity against HIV or HSV-1.
