Syn. Route 3
Route 1
this compound has been obtained by two similar ways:1) the condensation of 1-o-acetyl-2,3,5-o-tribenzoyl-beta-d-ribofuranose (i) with n6-benzoyl-9-(trimethylsilyl)adenine (ii) by means of trimethylsilyl perchlorate or trimethylsilyl trifluoromethanesulfonate in dichloroethane gives the tetrabenzoyladenosine (iii), which is finally debenzoylated with ammonia in methanol.2) the reaction of tetraacetyl-d-ribofuranose (iv) with dry hcl in ethyl ether gives the 1-chloro derivative (v), which is condensed with the silver salt of 2,8-dichloroadenine (vi) in refluxing xylene yielding the acetylated dichloroadenosine (vii). the hydrolysis of (vii) with ammonia in methanol affords 2,8-dichloroadenosine (viii), which is finally dechlorinated by hydrogenation with h2 over pd/baso4 in aqueous naoh.

Route 2
the esterification of 1h-imidazole-4,5-dicarboxylic acid (i) with etoh and sulfuric acid gives the diethyl ester (ii), which is brominated with nbs in acetonitrile, yielding the 2-bromo derivative (iii). the hydrolysis of (iii) by means of hot aqueous na2co3 affords the 2-bromo-1h-imidazole-4,5-dicarboxylic acid (iv), which is diazocoupled with the labeled diazonium ion (v) to provide the monolabeled azo acid (vi). the reaction of acid (vi) with 15nh4cl and dec in acetonitrile gives the doubly labeled azoamide (vii), which is reduced with h2 over pd/c in methanol to yield the doubly labeled 5-amino-1h-imidazole-4-carboxamide (viii). the cyclization of (viii) with sodium 13c-ethylxanthate (ix) in dmf affords the mercaptoxanthine (x), which is reduced to the hypoxanthine (xi) with raney ni and formic acid. the reaction of (xi) with pocl3 in hot n,n-dimethylaniline provides the triply labeled chloropurine (xii), which is submitted to enzymatic trans-glycosylation with 7-methylguanosine or thymidine and purine nucleoside phosphorylase (pnp) and thymidine phosphorylase (tp) to give the glycosylated chloropurine (xiii). finally, this compound is treated with 15nh4cl and khco3 in hot anhydrous dmso to afford the target tetralabeled adenine nucleoside.
