Synthesis of 2',3'-dideoxy-3'-C-(dihydroxyphosphinylmethyl)-adenosine and -thymidine 5, as well as of 2'-deoxy-2'-C-(dihydroxyphosphinylmethyl)- adenosine and -thymidine 9 was accomplished with the use of the universal carbohydrate precursor 3-deoxy-1,2;5,6-di-O-isopropylidene-3-C- (mesyloxymethyl)-α-D-allofuranose (1).

The synthesis of some 3'-C-branched-3'-deoxy adenine nucleosides is described. Starting from the known 3-deoxy-3-C-(hydroxymethyl)-1,2;5,6-di-O- isopropylidene-α-D-allofuranose (1), a versatile glycosylating agent, namely 1,2-di-O-acetyl-5-O-benzoyl-3-deoxy-3-C-(mesyloxymethyl)-β-D-ribofuranose (6), was prepared in three steps. Condensation of the latter with bis(trimethysilylated) N6-benzoyladenine in the presence of tin(IV) chloride gave the N9-β-nucleoside 7. Compound 7 was converted into (i) 9-[3-C- (azidomethyl)-3-deoxy-β-D-ribofuranosyl]adenine (10), (ii) 9-[3-C- (azidomethyl)-3-dideoxy-β-D-glycero-pent-2-enofuranosyl]adenine (14) and 9- [2-azido-3-C-(azidomethyl)-2,3-dideoxy-β-D-arabinofuranosyl]adenine (15), and (iii) 9-[3-deoxy-2-O,3-C-(methylene)-β-D-ribofuranosyl]adenine (16). None of the tested nucleosides showed marked cytostatic or antiviral activity in vitro.
