title: Open-chain carbocyclic analogs of adenosine with dihalovinyl unit as potential inhibitors of S-adenosyl-L-homocysteine hydrolase.
abstract: Vinylogously extended deoxyeritadenine derivatives were synthesized as acyclic/ carbocyclic analogues of the 6'-halo(homovinyl)adenosines, which are known to be potent inhibitors of S-adenosyl-L-homocysteine hydrolase. Swern oxidation of 9-[3-(t-butyldimethylsilyloxy)-4-hydroxybutyl]adenine (4) followed by Wittig olefination and desilylation gave access to ethyl 6-(adenin-9-yl)-4-hydroxy-2(E)-hexenoate (7) and 5-(adenin-9-yl)-1,1-dibromo-1-penten-3-ol (9). No inhibition of AdoHcy Hydrolase was observed with 7 and 9.
